Question

The positive charge in pentadienyl cation is delocalized over three carbon atoms.
(a) Draw the molecular orbitals of pentadienyl cation in order of increasing energy.
(b) How many nodes are present in the lowest and the highest energy molecular orbitals?

Accepted Answer

The number of nodes in the lowest molecular orbitals = 0The number of nodes in the highest molecular orbitals = 4

Answer

The number of nodes in the lowest molecular orbitals = 1The number of nodes in the highest molecular orbitals = 0

Answer

The number of nodes in the lowest molecular orbitals = 0The number of nodes in the highest molecular orbitals = 3

Answer

The number of nodes in the lowest molecular orbitals = 4The number of nodes in the highest molecular orbitals = 0
