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
- A1 > 2 > 3
- B1 > 3 > 2
- C3 > 2 > 1
- D2 > 3 > 1
Correct answer
A. 1 > 2 > 3
Step-by-step solution
C - C l bond length of these compounds in decreasing order is as follows C H 3 - C H 2 - C l > C H 2 = C H - C l > C 6 H 5 - C l C − Cl   bond   length   =   1 no .   of   resonating   structures C H 3 - C H 2 - C l no conjugation C H 2 = C H - C l Two resonating structures C 6 H 5 - C l Four resonating structures
