. Consider the molecules

CH4, NH3 and H2O. Which of the given statements is false?

bond angle

Best Answer

Correct Option is: D

CONCEPT: Bond angle depends on

1   % Of s character

2   inversely proportional to lone pairs on central atom

As all the three compounds are sp3 hybridised, all of them have the same % of s character. So, we need to check the 2nd condition which is lone pairs of electrons. In H2O molecules there are 2 lone pairs of electrons. This results in more electronic repulsion. Thus H - O - H bond angle is smaller than NH3 and CH4
