The Correct Option is D
Solution and Explanation
Stability of carbocation depends upon the number of hyperconjugative structures. More the hyperconjugative structure (i.e., more the number of hydrogen atoms attached directly to a-carbon atom), more is the stability of carbocation
Thus, the order of stability of given carbocation is
Thus, $(CH_{3})_{3}CC \overset{+}{H_{2}} (IV)$ is least stable carbocation among the given
Thus, the order of stability of given carbocation is
Thus, $(CH_{3})_{3}CC \overset{+}{H_{2}} (IV)$ is least stable carbocation among the given

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024
