Question

which of the following has a maximum bond angle [consider C N O S as central atom] $1) H_{2}O \\2) H_{2}S\\3) NH_{o} \\4) CH_{4}$

Answer 1

Among OF

2

, H

2

O and OCl

2

bond angle will depend upon electronegativity of surrounding atom as central atom is same and their hybridisation is also same . OCl

2

has unexpectedly greater angle due to bulky surrounding group Cl. Angle of OF

2

is smaller than that of H

2

O as bond angle is inversely to electronegativity.

All these are sp

3

hybridized. And have 2 lone pairs but ClO

2

has only 3 free electrons. Therefore, has highest bond angle.

Therefore, the bond angle order is: ClO

2

> OCl

2

> H

2

O > OF
