Question

A He molecule is not formed because
(a) N = N
(b) No > N.
© N, <N (d) No - N, = + ve​

Answer 1

Answer:

He molecule He2 is not formed.

Because, in He,

No. of bonding orbitals = No. of antibonding orbitals.

ie. Nb - Na = 0

So bond order = 1/2(Nb - Na)

= 0

'He' cannot exist as a diatomic molecule because of this reason.

Answer 2

Answer:

He molecule He2 is not formed.

Because, in He,

No. of bonding orbitals = No. of antibonding orbitals.

ie. Nb - Na = 0

So bond order = 1/2(Nb - Na)

= 0

'He' cannot exist as a diatomic molecule because of this reason.
