Question

question 1
according to molecular orbital theory, two separate 1s orbitals interact to form what molecular orbital(s)?
a s only
s and s*
b
c p only
d p and p*
question 2

according to molecular orbital theory, two separate px orbitals interact about the y - axis to form what molecular orbitals?
a s and s*
b p and p*
c s, s* and p
d s, s, p, and p

Explanation:

1. In molecular orbital theory, when two 1s orbitals interact, they form a bonding molecular orbital (σ) and an antibonding molecular orbital (σ). So for the interaction of two 1s orbitals, the result is σ and σ.
2. When two separate $p_x$ orbitals interact about the y - axis, they form a bonding π molecular orbital and an antibonding π* molecular orbital.

Answer:

Question 1: B. s and s*
Question 2: B. p and p*
