Solution and Explanation
The Hell-Volhard-Zelinsky reaction involves the halogenation of carboxylic acids at the α-position using a halogen (usually bromine) and a catalyst (like PBr₃ or Br₂ with a catalyst):
\[
\text{RCOOH} \xrightarrow{\text{Br}_2, \, \text{PBr}_3} \, \alpha\text{-Bromocarboxylic acid}
\]

- 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
