For the same alkyl (or) aryl group, the boiling point is more for

Given data : It is given to identify for the same alkyl (or) aryl group, the boiling point is more for 

Explanation

The temperature at which the surrounding air pressure matches the saturated vapor pressure of a liquid is known as the boiling point. Any material's boiling point is the temperature at which it changes from the liquid phase into the gas phase.

Alkyl halides' boiling points drop in the following order: $RI> RBr> RCl> RF$. This is due to the fact that when halogen size increases, van der Waals forces become more powerful and the boiling point rises as a result.

Hence the boiling point is more for  $RI$.

Hence, the correct option  (A).RI
