Number of following molecules showing planar symmetry is ____.
1 5
2 1
3 3
4 4
Explanation:
(a) is not planar (b) Ring is planar but hydrogens are not (c) Benzene is planar (d) The expected hybridization of N in Pyrrole is \({\text{s}}{{\text{p}}^{\text{3}}}\) but the unavailability of the lone pair and partial double bond character with \({\text{N}} \equiv {\text{C}}\) bonds, makes this molecule planar. (e) The expected hybridization of O in furan is \({\text{s}}{{\text{p}}^{\text{3}}}\) but one of the 2 lone pairs gets involved in resonance. Hence, the effective hybridization in \({\text{s}}{{\text{p}}^{\text{2}}}\) which means, furan is planar.
