Question

Which of the following molecule(s) has/have highest number of the features given below?
1. Have three traslational degrees of freedom.
2. Have two rotational degrees of freedom.
3. Triatomic and non linear
4. Triatomic and linear

• A. $C{O}_2$
• B. $S{O}_2$
• C. $He$
• D. $N_2$

Answer 1

The correct option is A $C{O}_2$

The features contained by the molecules are as follows;
$C{O}_2$ Features 1, 2, 4
$S{O}_2$ Features 1, 3
$He$ Features 1
$N_2$ Features 1, 2

Highest number of features are shown by $C{O}_2$.
