Question

How many degree of freedom of benzene

Answer 1

Answer:

The center of mass motion of the entire molecule accounts for 3 degrees of freedom. In addition, the molecule has two rotational degrees of motion and one vibrational mode.

Answer 2

Answer:

Benzene has 30 degrees of freedom.

Explanation:

What is the Degree of freedom?

• It is defined as the number of independent ways in which a molecule of gas can move is called as degree of freedom.

Degree of freedom in Benzene:

• Benzene is a non linear or ring structure.
• For the degree of freedom for non linear structure,

Degree of freedom= (3N - 6)

where,

• N = number of atoms in benzene molecule which is 12.
• 2 rotational, 1 vibrational and 3 transitional rotations are present in benzene.

So,

Degree of freedom of benzene= ( 3×12 - 6)

= 36 - 6

= 30

So, the degree of freedom of benzene is 30.
