In SOCl ₂ the Cl - S - Cl and Cl - S - O bond angle are
Options
- A130^ and 115^
- B106^ and 96^
- C107^ and 108^
- D96^ and 106^
Correct answer
D. 96^ and 106^
Step-by-step solution
SOCl ₂ has one S =0 double bond and two S - Cl single bond. Hybridisation of S= 1 2 [6+2-0+0]=4 Thus, S is s p^3 . Since, SOCl ₂ has only three sigma bond, therefore it has one lone pair of electrons on S atom and hence its shape is pyramidal and the bond angle are less than 109.5^ due to repulsion between lone pairs. Further, since -electrons of the S = O bonds are more polarised, therefore, they repel the bond pair of S - Cl bond. Thus, making Cl - S - O bond larger than Cl - S - Cl bond angle.
