$CH_3I$

Vedclass · Answer

(A) The boiling points of haloalkanes increase with an increase in the size and mass of the halogen atom due to the increase in magnitude of van der Waals forces. $CH_3F$ (boiling point: $-78.4 \ ^oC$),$CH_3Cl$ (boiling point: $-24.2 \ ^oC$),$CH_3Br$ (boiling point: $3.6 \ ^oC$),and $C_2H_5Cl$ (boiling point: $12.3 \ ^oC$) are gases at room temperature. $CH_3I$ has a boiling point of $42.4 \ ^oC$,which makes it a liquid at room temperature. Therefore,the correct option is $(A)$.
