Question

Find the bond order of following: 

(i) H₂ molecule 

(ii) O₂ molecule 

(iii) N₂ molecule 

(iv) Cl₂ molecule 

(v) CO molecule

Answer 1

(i) H₂ molecule has single bond (H - H), so bo order will be 1. 

(ii) O₂ molecule has double bond (0 = 0), so bond ord will be 2. 

(iii) N₂ molecule has triple bond (N = N), so bond ord will be 3. 

(iv) Cl₂ molecule has single bond (Cl - Cl) so bond ord will be 1. 

(v) CO molecule is represented by imm, so its bo order will be 3.
