Chemical Bonding And Molecular Structure Ques 97

97. In which of the following, the bond angle is maximum?

[2001]

(a) $NH_3$

(c) $NH_4^{+}$

(b) $SCl_2$

(d) $PCl_3$

Show Answer

Answer:

Correct Answer: 97.(c)

Solution:

(c) In all the species, the center atom is $s p^{3}$ hybridized. But only in $NH_4^{+}$, no lone pair of electrons are present. Thus, it has maximum bond angle.
