Consider the molecules CH₄, NH₃ and H₂O.

Which of the given statements is false?

The H $$-$$ O $$-$$ H bond angle in H₂O is smaller than the H $$-$$ N $$-$$ H bond angle in NH₃.

The H $$-$$ C $$-$$ H bond angle in CH₄ is larger than the H $$-$$ N $$-$$ H bond angle in NH₃.

The H $$-$$ C $$-$$ H bond angle in CH₄, the H $$-$$ N $$-$$ H bond angle in NH₃, and the H $$-$$ O $$-$$ H bond angle in H₂O are all greater than 90^o.

The H $$-$$ O $$-$$ H bond angle in H₂O is larger than the H $$-$$ C $$-$$ H bond angle in CH₄.
