Hybridisation of the underlined atom is affected when:

Options

  1. AC ¯ H 3 COOH is decarboxylated
  2. BCH 3 C ¯ H 2 OH is dehydrated
  3. CCH 3 C ¯ H 3 is chlorinated
  4. DC ¯ 6 H 6 is nitrated

Correct answer

B. CH 3 C ¯ H 2 OH is dehydrated

Step-by-step solution

C H 3 COOH → C ¯ H 4 + CO 2 sp 3 → sp 3 CH 3 C H 2 OH → CH 2 = C H 2 sp 3 → sp 2 CH 3 - C H 3 → CH 3 - C H 2 - Cl sp 3 → sp 3 C 6 H 6 → C 6 H 5 NO 2 sp 2 - sp 2
