Question

Which of the following molecule(s) has/have $d_n-p_{\pi }$ bonding?

• A. $H_2{S}_2{O}_3$
• B. $P_4{O}_{10}$
• C. $S{O}_3$
• D. $P_4{S}_{10}$

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A $H_2{S}_2{O}_3$
B $S{O}_3$
C $P_4{S}_{10}$
D $P_4{O}_{10}$

In $H_2{S}_2{O}_3$ $S$ empty $d$ orbital and $O$ has electrons in $P$ orbital.

Hence, it has $d_n$$-$$P_n$ bonding.

In $P_4{O}_{10}$ $P$ have empty $d$ orbital and $O$ has electrons in $P$ orbital

Hence, it has $d_n$$-$$P_n$ bonding.

In ${SO}_3$ $S$ have empty $d$ orbital and $O$ has electrons in $P$ orbital.

Hence, it has $d_n$$-$$P_n$ orbital.

Similarly in $P_4{S}_{10}$
