Experimental evidence has also shown that the H-N-H bond angles in ammonia (NH 3 ) are 107 o and the H-O-H bond angles in water are 105 o . It is clear from these bond angles that the non-bonding pairs of electrons occupy a reasonable amount of space and are pushing the hydrogen atoms closer together compared to the angles found in methane....
