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 does.
