When number of bonds means single, double , triple between carbon atoms increases the bond length decreases. Hence, option C is correct.
The distance between the centers of two covalently bonded atoms is defined as the bond length. The length of the bond is obtained by the number of bonded electrons i.e., the bond order. The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length or it can be said that bond order is inversely proportional to the bond length.
Generally, the length of the bond between two atoms is approximately equal to the sum of the covalent radii of the two atoms. Therefore, bond length between to carbon atoms increases in the following order: triple bond < double bond < single bond.

For the exothermic reaction represented above, carried out at 298K, the rate law is as follows.
Rate = k[H2][I2]
Predict the effect of each of the following changes on the initial rate of the reaction and explain your prediction.
(a) Addition of hydrogen gas at constant temperature and volume
(b) Increase in volume of the reaction vessel at constant temperature
(c) Addition of catalyst. In your explanation, include a diagram of potential energy versus reaction coordinate.
(d) Increase in temperature. In your explanation, include a diagram showing the number of molecules as a function of energy.
The rate law demonstrates that as the concentration of H₂ rises, so does the rate of the reaction.
This is due to the fact that the number of effective collisions between H₂ and I₂ in order to produce HI also increases as the number of H₂ molecules increases.
b) As the vessel's volume increases, reactant molecules are able to move farther apart from one another, which results in a decrease in the number of effective collisions in a given time period. As a result, the rate of the reaction slows down.
c) The addition of a catalyst to the reaction mixture speeds up the reaction. This is due to the fact that, when a catalyst is present, the reactant molecules choose a reaction pathway with a lower activation energy. Since the pathway has a lower activation energy, the number of collisions that are effective enough to form a product increases over time. The presented plot of energy against reaction coordinate demonstrates this.
d) The number of reactant molecules with higher energy than activation energy rises with system temperature. As a result, the rate of reaction increases as well as the number of successful collisions.
What is the constant rate?For basic reactions, molecular dynamics simulations can be used to determine the rate constant. Calculating the molecule's mean residence time in the reactant state is one option.
This method can be used in small systems with short residence times, but it is not widely used because reactions are typically rare at the molecular scale.

In the following reaction, 24 g of CH₂ (methane) react completely with 96 g of O₂ to form 66 g of CO₂. How many grams of H₂O are formed? CH4 + 20₂ → CO₂ + 2H₂O
The reaction of 24 g of CH₄ (methane) with 96 g of O₂ will form 66 g of CO₂ and 132 g of H₂O.
What is a Chemical Reaction?A chemical reaction is a process that causes one group of chemical components to change chemically into another.
In this reaction, one molecule of CH₄ reacts with two molecules of O₂ to form one molecule of CO₂ and two molecules of H₂O. The balanced chemical equation for this reaction is:
CH₄ + 2O₂ -> CO₂ + 2H₂O
Since 24 g of CH₄ reacts with 96 g of O₂, the number of moles of CH₄ and O₂ can be calculated.
\
The number of moles of CO₂ and H₂O can also be calculated using the balanced equation and the number of moles of CH₄ and O₂.
The number of grams of CO₂ and H₂O can then be calculated using the moles and the molar mass of each substance.
In this case, the number of grams of CO₂ formed is 66 g, and the number of moles of CO₂ is 66 g / (44.01 g/mol) = 1.5 moles.
Since two moles of H₂O are produced per mole of CO₂, the number of moles of H₂O is 2 x 1.5 = 3 moles.
The number of grams of H₂O can be calculated as 3 moles x (18.015 g/mol) = 54.045 g. So, the total amount of H₂O formed is 54.045 g.

Three or more elements make up ternary compounds. It is analogous to naming basic ionic compounds to name binary (two-element) molecular molecules. The first component of the formula is only the element's name mentioned. By taking the element name's stem and adding the suffix -ide, the second element is given a name.

What do you mean by Functional Group?A functional group is a specific molecular grouping of atoms that is responsible for the characteristic chemical reactions of a molecule. These groups can consist of a few atoms or several atoms joined together, and they dictate the reactivity and physical properties of the molecule. The most common functional groups in organic chemistry include alcohols, carbonyls, carboxylic acids, amines, and alkanes.
Functional groups play a critical role in determining the properties and reactivity of organic molecules. For example, alcohols have a hydroxyl (-OH) functional group that makes them polar and reactive with other polar substances. On the other hand, alkanes have a nonpolar hydrocarbon (-C-C-) functional group that makes them nonpolar and unreactive.
In chemistry, an alcohol is a type of organic compound that contains a hydroxyl (-OH) functional group. Alcohols are characterized by the presence of this functional group, which gives the molecule its characteristic polar and reactive properties.
A carboxylic acid is a type of organic acid that contains a carboxyl (-COOH) group, which is a functional group composed of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl (-OH) group. Carboxylic acids are widely found in nature and have a sour taste. Examples include acetic acid (found in vinegar), citric acid (found in citrus fruits), and formic acid (found in ant bites).
Amines are a type of organic compound that contain nitrogen as a central atom and are derived from ammonia (NH3) by replacing one, two, or all three of the hydrogens with organic groups (alkyl or aryl groups). Depending on the number of hydrogen atoms replaced, amines can be classified as primary (one hydrogen replaced), secondary (two hydrogens replaced), or tertiary (all three hydrogens replaced). Amines are commonly used as intermediates in the synthesis of pharmaceuticals, agrochemicals, and dyes. They also have a range of biological activities, including serving as neurotransmitters in the human body.

To find the volume of CO2 produced from the combustion of 10.50 L of C2H6 (measured at 27°C and 778 torr), we can use the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in kelvins.
First, we need to convert the temperature to kelvins: T = 27°C + 273 = 300 K. Next, we need to find the number of moles of C2H6. We can use the volume of the gas and the pressure to find the number of moles: n = (PV)/(RT) = (778 * 10.50 L)/(0.0821 Latm/K * 300 K) = 0.367 moles.
Next, we need to use the balanced chemical equation to find the number of moles of CO2 produced: 4 moles CO2 are produced for every 2 moles of C2H6. Thus, 0.367 moles of C2H6 produces 0.367 * 2/4 = 0.184 moles of CO2.
Finally, we can use the ideal gas law to find the volume of CO2 produced at STP (standard temperature and pressure, which is 0°C and 1 atm): V = (nRT)/P = (0.184 moles * 0.0821 Latm/K * 273 K) / 1 atm = 5.32 L.
