Reactions of Ethers and Epoxides 18-44 Predict the products of the following ether cleavage reactions: (a) (b) CH3 CH2CH3 CF3CO2H H20 2 H3C CH3 HI 7 (c) CH3 H2C=CH-0-CH2CH3 HI H2O ? (d) CH3CCH2-O-CH2CH3 CH3 HI H20 ?
Answers
The product would be: a. [tex]CH_3CH_2^+ + CH_3CH_2OH + CF_3CO^{2-}[/tex]
b. [tex]H_3C-I + CH_3CH_2-I + H_2O[/tex]
c. [tex]H_3CCH_2OH + CH_3CH_2I[/tex]
d. [tex]CH_3CCH_2OH + CH_3CH_2I[/tex]
(a) The reaction of an ether with a strong acid like [tex]CF_3CO_2H[/tex] can lead to the cleavage of the ether bond and the formation of two carbocations. In this case, the product would be:
[tex]CH_3CH_2^+ + CH_3CH_2OH + CF_3CO^{2-}[/tex]
(b) The reaction of an ether with HI can lead to the cleavage of the ether bond and the formation of two alkyl halides. In this case, the product would be:
[tex]H_3C-I + CH_3CH_2-I + H_2O[/tex]
(c) The reaction of an ether with HI and subsequent reaction with water can lead to the formation of an alcohol and an alkyl halide. In this case, the product would be:
[tex]H_3CCH_2OH + CH_3CH_2I[/tex]
(d) The reaction of an ether with HI and subsequent reaction with water can lead to the formation of an alcohol and an alkyl halide. In this case, the product would be:
[tex]CH_3CCH_2OH + CH_3CH_2I[/tex]
Note that in both (c) and (d), the reaction can proceed via an SN1 mechanism in which the leaving group (the ether oxygen) departs to form a carbocation intermediate.
The carbocation can then react with the nucleophilic iodide ion to form the alkyl halide, while the protonated alcohol can undergo deprotonation to form the final alcohol product.

(a) Acid-catalyzed hydrolysis reaction
(b) Nucleophilic substitution reaction
(c) Nucleophilic substitution reaction
(d) Acid-catalyzed hydrolysis reaction
When it comes to predicting the products of ether cleavage reactions, it's important to consider the specific conditions of each reaction. Here are the predictions for the reactions you provided:
(a) CH3 CH2CH3 CF3CO2H H20 2 H3C CH3
This is an acid-catalyzed hydrolysis reaction, which will break the ether bond and form two alcohol products. The specific products will depend on the specific ether being cleaved, but in general, the products will be a primary alcohol (CH3CH2OH) and a tertiary alcohol (H3CCH3OH).
(b) HI 7
This is a classic example of a nucleophilic substitution reaction, in which the iodide ion (I-) acts as a nucleophile and attacks the ether carbon to break the bond and form an alkyl iodide product. In this case, the products will be H3CCH2I and CH3I.
(c) CH3 H2C=CH-0-CH2CH3 HI H2O
This reaction is also a nucleophilic substitution reaction, but the specific conditions are different. In this case, the hydroxide ion (OH-) from water acts as a nucleophile to attack the ether carbon and break the bond. The products will be H3CCH=CH2 (an alkene) and CH3OH (a primary alcohol).
(d) CH3CCH2-O-CH2CH3 CH3 HI H20
This is another acid-catalyzed hydrolysis reaction, similar to part (a). The ether bond will be broken and two alcohol products will be formed. The specific products will depend on the specific ether being cleaved, but in general, the products will be a primary alcohol (CH3CH2OH) and a secondary alcohol (CH3CH2CH2OH).

A gas has a volume of 500cm3 when a pressure of 100,00N is exacted on it what will be it's volume if the pressure is changed to 150mm mecury at same temperature
Answers
Answer:
See explanation below
Explanation:
At first sight, it seems that the innitial pressure of 100,00 N would be 100,00 N/m² because pressure does not have units of newton alone. If this is true, then the calculations are the following (If it's not, but it's actually mm Hg, then skip the part of the conversion, and just do the procedure of solving for the volume).
The innitial pressure is 100 N/m² or simply 100 Pa. As the second pressure is in mm Hg, let's convert the Pascal units to mm Hg:
1 Pa -----> 0.007501 mm Hg
100 ---------> X
X = 100 * 0.007501 / 1 = 0.7501 mmHg
Now that we have the innitial pressure in mm Hg, and the temperature remains constant, we use the Boyle's law to solve for this:
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
Using this expression, let's solve for V₂:
V₂ = 0.7501 *¨500 / 150
V₂ = 2.5 cm³
Now, it's the innitial pressure is 100 mm Hg then the volume:
V₂ = 100 * 500 / 150
V₂ = 333.33 cm³
Check the units of the innitial pressure, one of these results should be the correct answer. If it's not, then please post again the question with the correct units.

N2 + 3H2 → 2NH3 How many grams of hydrogen are necessary to react completely with 853.42g of nitrogen in the above reaction?
Answers
Answer: 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.
Explanation:
The balanced chemical reaction is :
[tex]N_2+3H_2\rightarrow 2NH_3[/tex]
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
[tex]\text{Number of moles of nitrogen}=\frac{853.42g}{28g/mol}=30.479moles[/tex]
According to stoichiometry:
1 mole of [tex]N_2[/tex] react with = 3 moles of [tex]H_2[/tex]
30.479 moles of [tex]N_2[/tex] will react with=[tex]\frac{3}{1}\times 30.479=91.437moles[/tex] of [tex]H_2[/tex]
Mass of [tex]H_2[/tex] =[tex]moles\times {\text {Molar mass}}=91.437mol\times 2g/mol=182.87g[/tex]
Thus 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.

The transfer of ____________ is achieved when eating and feeding exists
Answers
Answer:
the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.
The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.
What is energy?The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.
This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.
Therefore, the transfer energy is achieved when eating and feeding exists.

How many kilograms of chlorine gas is needed to produce 45.0 grams of hydrochloric acid?
Answers
Answer:
43.76 g = 0.04376 Kg
Explanation:
The equation of the reaction is given as;
H2 + Cl2 --> 2HCl
From the equation;
1 mol of Cl2 produces 2 mol of HCl
Converting to mass;
Mass = Number of mol * Molar mass
Cl2;
Mass = 1 mol * 70.906 g/mol = 70.906 g
HCl;
Mass = 2 mol * 36.458 g/mol = 72.916 g
This means;
70.906 g of Cl2 produces 72.916 g of HCl
x g of Cl2 would produce 45g of HCl
70.906 = 72.916
x = 45
x = 45 * 70.906 / 72.916
x = 43.76g

Explanation:
i hope it helps u
Medium in which the sound waves are travelling.
Explanation:-
To understand this first we need to know that there are 2 types of waves; Mechanical waves and Electromagnetic waves.
Sound waves are mechanical waves meaning they need a medium to propagate. So this clarifies that they will obviously depend on the properties of the medium.
As far as the topic of speed is concerned;
sound travels fastest in solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
