Chemical Bonding and Molecular Structure - Result Question 71
####72. Among the following ions the $p \pi-d \pi$ overlap could be present in
(a) $NO_2^{-}$
(b) $NO_3^{-}$
(c) $PO_4^{3-}$
(d) $CO_3^{2-}$
[2000]
Show Answer
Solution:
- (c) In $P-O$ bond, $\pi$ bond is formed by the sidewise overlapping of $d$-orbital of $P$ and $p$ orbital of oxygen. Hence it is formed by $p \pi$ and $d \pi$ overlapping.
[O-]P([O-])([O-])([O-])[O-]
