Question

Among CH4, CO2, H2O and SO2 the bond angle is the highest in (A) CH4 (B) CO2 (C) H2O (D) SO2

Tardigrade Admin · Accepted Answer

As the number of lone pairs of electrons increases, bond angle decreases.
The number of lone pair in

C H_{4}, C O_{2}, H_{2} O

and

S O_{2}

respectively are

0, 0, 2

and

1. S o, C H_{4}

and

C O_{2}

will have the maximum bond angle.
Also, multiple bond orbitals repel other orbitals more strongly than single bond orbital.
Thus, the bond angle will increase.
As

C H_{4}

has single bonds whereas

C O_{2}

has double bonds.
Therefore,

C O_{2}

has the highest bond angle.
