The translational degrees of freedom (ft)androtationaldegreesoffreedom(fr)ofCH4\left(f_t\right) and rotational degrees of freedom \left(f_r\right) of \mathrm{CH}_4 molecule are:

Options

  1. Aft=2f_t=2 and fr=2f_r=2
  2. Bft=3f_t=3 and fr=3f_r=3
  3. Cft=3f_t=3 and fr=2f_r=2
  4. Dft=2f_t=2 and fr=3f_r=3

Correct answer

B. ft=3f_t=3 and fr=3f_r=3

Step-by-step solution

Since CH4\mathrm{CH}_4 is polyatomic Non-Linear D.O.F of CH4\mathrm{CH}_4 T. DOF =3=3 RDOF=3\mathrm{RDOF}=3
