Question

Which of the following gas is linear?

• A. $CO_2$
• B. $SO_2$
• C. $NO_2$
• D. $SO_3$

Answer 1

Answer: (A)

$CO_2$

Answer 2

The molecule having sp hybridization will have linear shape. $\because SO_{2},\, SO_{3}$ and $N O_{2}$ have $sp^{2}$ hybridisation. $\therefore$ They are triangular planar in shape. $\because C$ in $CO _{2}$ is sp hybridised. $\therefore CO _{2}$ is linear in shape.
