Question

1. When you fill in a molecular orbital diagram with electrons, the electrons have opposite spins.

a. True

b. False

2. Pi molecular orbitals have electron density on the internuclear axis.

a. True

b. False

3. A molecular orbital is:

a. an orbital that encompasses more than one molecule

b. an orbital that encompasses an entire molecule, and results from the interaction of atomic orbitals

c. the same as an atomic orbital

d. a number based on the number of electrons in bonding and antibonding orbitals that indicates how stable a bond is

e. an orbital that contains more than two electrons

Answer 1

1. Similar to that of an atomic orbital, molecular orbital also obeys Hund's rule and Pauli's exclusion principle,

Which means the electron present in the molecular orbital will have opposite spin.

Therefore option - ''a" is correct, i.e true

2. Pi molecular orbitals have electron density present above and below the internuclear axis, hence the given statement is false.

Correct option is "b", i.e false

3. A molecular orbital is an orbital which encompasses the complete molecule, and is formed by interaction of atomic orbitals, hence option- b is correct.
