The translational degrees of freedom (ft)\left(f_t\right) and rotational degrees of freedom (fr)\left(f_r\right) of CH4\mathrm{CH}_4 molecule are:

Multiple Choice Options

  • A ft=2f_t=2 and fr=2f_r=2
  • B ft=3f_t=3 and fr=3f_r=3
  • C ft=3f_t=3 and 4 fr=2f_r=2 $
  • D ft=2f_t=2 and fr=3f_r=3

Step-by-Step Verified Solution

For non-linear polyatomic molecules, both translational and rotational degree of freedom have same value and is equal to 3.
