JEE Main Chemistry question

The incorrect statement regarding bonding molecular orbitals is

(A)A bonding molecular orbital possesses less energy than the combining atomic orbitals
(B)Bonding molecular orbitals have low electron density between the two nucleiCorrect
(C)Every electron in a bonding molecular orbital contributes to attraction between the atoms
(D)They are formed when the lobes of the combining atomic orbitals have the same sign

Answer: (B)

Solution

Bonding molecular orbitals are characterised by a build-up of electron density in the region between the two nuclei; this concentrated electron density is precisely what attracts both nuclei and holds the atoms together. Statement
