Q. The bond angle in water molecule is less than in ammonia molecule, due to the

Rajasthan PMTRajasthan PMT 2011

Solution:

The shape of ammonia molecule is trigonal pyramidal due to repulsion between $ lp-bp $ (which is more than $ bp-bp $ repulsion). Thus, the and between the bond pairs in ammonia is reduced to $ {{107}^{o}} $ from $ {{109.5}^{o}} $ .
