Question

Among the following molecules, the one with the largest bond angle at the central atom is

(a) ClF₃

(b) POCl₃

(c) BCl₃

(d) SO₃

Answer 1

Answer is : (a) ClF₃

The bond angle depends upon the electronegativity of the central atom. More is the electronegativity of the central, larger is the bond angle. Thus, among the given central atom Cl has the highest electronegativity. Therefore, ClF₃ has the largest bond angle at the central atom.
