Which of the following statements about molecular orbitals is true?

Sagot :

Answer:

a. When two p orbitals of similar phase overlap side-by-side, a  π ∗ antibonding molecular orbital is formed.

b. When two p orbitals of opposite phase overlap side-by-side, a  π bonding molecular orbital is formed.

c. A  π  bonding molecular orbital is higher in energy than the two atomic p orbitals from which it is formed.

d. A  π ∗  bonding molecular orbital is higher in energy than the two atomic p orbitals from which it is formed.

if these are your options then your answer would be D

Explanation:

A  π ∗ antibonding molecular orbital is higher in energy than the two atomic p orbitals from which it is formed.

Antibonding molecular orbitals have higher energy than the two atomic p orbitals from which it is formed. On the other hand, bonding atomic orbitals have a lower energy than the two atomic p orbitals from which it is formed.

A  π ∗ antibonding molecular orbital is formed when two p orbitals of opposite phase overlap side-by-side.
