The correct order of Sulphur oxygen bond order in SO 3 , S 2 O 3 2 - and SO 4 2 - are
Options
- ASO 4 2 - < S 2 O 3 2 - < SO 3
- BSO 4 2 - < SO 3 < S 2 O 3 2 -
- CS 2 O 3 2 - < SO 4 2 - < SO 3
- DS 2 O 3 2 - < SO 3 < SO 4 2 -
Correct answer
C. S 2 O 3 2 - < SO 4 2 - < SO 3
Step-by-step solution
The SO 3 has the bond order of two. The bond order of SO 4 2 - :- It has the four resonating structure. It has the four equivalent oxygen atoms and six bonds between the sulphur and oxygen. Bond order = 6 4 = 1 . 5 The bond order of S 2 O 3 2 - :- It has the three resonating structure and there are four bonds formed between the sulphur and oxygen atoms. Bond order = 4 3 = 1 . 33 Hence, the correct order of Sulphur oxygen bond order is S 2 O 3 2 - < SO 4 2 - < SO 3 .
