Question

Why is the bond angle in a water molecule less than the bond angle of methane?
a. The central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs.
b. The central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs.
c. The central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair.
d. The central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane

Answer 1

well i think it's A because oxygen has two lone pairs and lone pairs occupy more space so in other words ..they give more repulsion.... Thus reducing the bond angle :)

Answer 2

you are correct sir. thank you very much. @SyedMohammed98
