Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Primary allyl carbocation is stabilised only by resonance effect whereas secondary and tertiary allyl carbocations are stabilised by resonance, hyperconjugation and inductive effect.
$ \therefore $ The stability of carbocations in decreasing order is $ 3^{\circ} $ allyl carbocation $ > 2^{\circ} $ allyl carbocation $ > 1^{\circ} $ allyl carbocation.

- 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

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
