Which of the following pairs of compounds, 1-chloropropane and isopropyl chloride, would you expect

Q: What is the correct answer for CBSE12?

The correct answer is B. Boiling points of isomeric haloalkanes decrease with increasing branching. Isopropyl chloride (2-chloropropane) is branched, while 1-chloropropane is linear. Branching reduces the surface area available for van der Waals interactions, leading to weaker intermolecular forces and thus a lower boiling point for the branched isomer (isopropyl chloride) compared to the linear isomer (1-chloropropane).
