Given below are two statements : In the light of the above statements, choose the correct answer from the options given below :

  1. Both Statement I and Statement II are true
  2. Both Statement I and Statement II are false
  3. Statement I is true but Statement II is false
  4. Statement I is false but Statement II is true

Answer

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

Solution

Statement I:

C6H5-CH2-CH=CH2 + HBr C6H5-CH2-CHBr-CH3 (Markovnikov addition via the 2° carbocation)

The C–Br carbon carries four different groups (H, Br, CH3, CH2C6H5) ⇒ a secondary alkyl bromide with a chiral carbon

(even if a hydride shift gives the benzylic cation, the product C6H5-CHBr-CH2-CH3 is again a chiral 2° bromide) ⇒ Statement I is true.

Statement II:

Sandmeyer: ArN2+X- CuCl/HCl ArCl and ArN2+X- CuCN/KCN ArCN

Gattermann: ArN2+X- Cu/HCl ArCl (or Cu/HBr ⇒ ArBr) — aryl cyanides are not prepared this way

⇒ Statement II is false.

Answer: (3)
