JEE Mains · Chemistry · STD 12 - 6. Haloalkanes and Haloarenes

Given below are two statements:

Statement I: \(3\)-phenylpropene reacts with HBr and gives secondary alkyl bromide having a chiral carbon atom as the major product.

Statement II: Aryl chlorides and aryl cyanides can be prepared by Sandmeyer reaction as well as Gattermann reaction.

In the light of the above statements, choose the correct answer from the options given below

  1. A Both Statement I and Statement II are true
  2. B Both Statement I and Statement II are false
  3. C Statement I is true but Statement II is false
  4. D Statement I is false but Statement II is true
Verified Solution

Answer & Solution

Correct Answer

(C) Statement I is true but Statement II is false

Step-by-step Solution

Detailed explanation

Statement I: When \(3\)-phenylpropene reacts with \(HBr\), protonation of the alkene occurs to form a secondary carbocation. \(C_6H_5-CH_2-CH=CH_2 + H^+ \rightarrow C_6H_5-CH_2-CH^+-CH_3\) This secondary carbocation undergoes a \(1,2\)-hydride shift to form a more stable,…
