For each of the following compounds, predict the energy barrier to rotation (looking down any one of the C—C bonds). Draw a Newman projection and then compare the staggered and eclipsed conformations. Remember that we assigned 4 kJ/mol to each pair of eclipsing H’s and 6 kJ/mol to an H eclipsing a methyl group:
(a) 2,2-Dimethylpropane
(b) 2-Methylpropane
(a) The steric hindrance brought on by the large methyl groups in 2,2-dimethylpropane results in a rather high energy barrier to rotation.
The lowest amount of energy necessary for a chemical reaction to take place is referred to as the energy barrier, also known as the activation energy. It is the amount of energy needed for the reactants to reach the transition state or the reaction's maximum energy location. The size of the energy barrier controls how quickly a reaction happens; a higher barrier causes a slower rate of reaction. Catalysts are frequently utilised to offer an alternate pathway that takes less energy to move forward in order to lower the energy barrier. Grasp chemical kinetics and creating chemical reactions with appropriate reaction rates require an understanding of the energy barrier concept.

The given reaction involves the reduction of a ketone using NaBH4 and subsequent exchange of a proton with deuterium in D2O.
In the first step, NaBH4 donates a hydride ion (H-) to the carbonyl carbon of the ketone, forming an alkoxide intermediate. The hydride ion acts as a nucleophile, attacking the electrophilic carbon of the carbonyl group. In the second step, the alkoxide intermediate is protonated by D2O, leading to the formation of the corresponding alcohol and release of NaOD. The proton exchange with D2O results in the replacement of a proton by a deuterium atom. The final products are the deuterated alcohol and NaOD. The curved arrows in the mechanism represent the flow of electrons, and it is essential to show all the nonbonding electron pairs involved in each step.

What is Molecular formula?The molecular formula of a compound is defined as the formula which gives the actual number of atoms of various elements present in one molecule of the compound.
Here 92.24 % 'C' = 92.24 g
7.76 % 'H' = 7.76 g
Number of moles (n) = Given mass / Molar mass
'n' of 'C' = 92.24 / 12 = 7.68 moles
'n' of 'H' = 7.76 / 1 = 7.76 g
Number of atoms of 'C' = 7.68 / 7.68 = 1
Number of atoms of 'H' = 7.76 / 7.68 = 1

you would expect human red cells to shrink in which of the following solutions: 0.2m nacl 0.2m surcrose 0.2m urea
You would expect human red cells to shrink in 0.2 M NaCl. The correct answer is A.
Red blood cells have an ion concentration of roughly 300mM, or 300 milliosmolality. Essentially, it indicates that the concentration of all the dissolved ions in a red blood cell is roughly 300 mM, or 0.3M.
Where there is a higher concentration of water, it moves toward a lower concentration. Water flows from lower osmolarity to higher osmolarity, or put another way (since water is higher in concentration in a lower osmolarity solution).
Since a solution of 0.2M NaCl has an osmolarity of 0.4M, the water concentration in red blood cells is higher. This implies that the red blood cell will shrink and shrivel when water flows OUT of it.
Urea 0.2M is a dissolved solute even though it is not ionic. Water will somewhat enter the red blood cell since it is less concentrated than the red blood cell. (assumes red blood cells with 0.3M osmolarity).
In a hypotonic condition, a red blood cell will enlarge and go through hemolysis (burst). A red blood cell will crenate and lose water when it is placed in a hypertonic solution (shrivel).
