Question

The correct order of increasing bond length of $$C - H,\,C - O,\,C - C$$     and $$C = C$$  is

A. $$C - C < C = C < C - O < C - H$$
B. $$C - O < C - H < C - C < C = C$$
C. $$C - H < C - O < C - C < C = C$$
D. $$C - H < C = C < C - O < C - C$$  
Answer :   $$C - H < C = C < C - O < C - C$$
Solution :
$$\eqalign{ & C - H:0.109\,nm \cr & C = C:\,0.134\,nm \cr & C - O:\,0.143\,nm \cr & C - C:\,0.154\,nm \cr & \therefore \,\,{\text{Bond length order is}} \cr & C - H < C = C < C - O < C - C \cr} $$
