The shape of NH₃ is pyramidal rather than planar because
Aof hydrogen bonding
Bnitrogen is sp hybridised
Cthe lone pair on N repels the bonding pairs
Dit has no lone pairs
Answer & Solution
Correct answer: C. the lone pair on N repels the bonding pairs
N has one lone pair + three bonds (sp³). Lone-pair–bond-pair repulsion pushes the H atoms down into a trigonal pyramid.
