Ques. 1JEE Main 2026, 2 April (Evening Shift)

Correct statements regarding alkyl halides (R–X) among the following are : Choose the correct answer from the options given below :

  1. A, B and C Only
  2. B and D Only
  3. A and E Only
  4. D and E Only

Answer

(3) A and E Only

Solution

A: in less polar alcohol the alkoxide/hydroxide acts as a strong base, so dehydrohalogenation (elimination) is favoured ⇒ true.

B: SN1 rate depends on carbocation stability; (C6H5)2 CH (two phenyl rings for resonance) is more stable than C6H5 CH2 ⇒ the order is reversed ⇒ false.

C: in aryl halides the C–X bond has partial double-bond character (resonance, sp² carbon), so they are much less reactive than alkyl halides ⇒ false.

D: allyl chloride CH2=CH-CH2Cl also contains a C=C bond – it is an allylic halide (a haloalkene), not a haloalkyne ⇒ false.

E: ROH + SOCl2 → RCl + SO2 + HCl; the C–O bond of phenol has partial double-bond character and is not replaced ⇒ true.

∴ A and E only.

Answer: (3)
