Consider the following three halides : (1) C H 3 - C H 2 - C l (2) C H 2 = C H - C l (3) C 6 H 5 - C l Arrange C - C l bond length of these compounds in decreasing order -

Options

  1. A1 > 2 > 3
  2. B1 > 3 > 2
  3. C3 > 2 > 1
  4. D2 > 3 > 1

Correct answer

A. 1 > 2 > 3

Step-by-step solution

(1) C H 3 - C H 2 - C l R . S . = 0 (2) C H 2 = C H - C l R . S . = 2 (3) C 6 H 5 - C l R . S . = 4 R . S . ∝ 1 B o n d l e n g t h o f s i n g l e b o n d
