For the same alkyl group, how do boiling points of alkyl halides vary?
ARCl > RBr > RI > RF
BRBr > RI > RCl > RF
CRI > RBr > RCl > RF
DRF > RCl > RBr > RI
Answer & Solution
Correct answer: C. RI > RBr > RCl > RF
Larger halogen atoms have more electrons, giving stronger van der Waals forces and higher boiling points.
