Question:
Which isomer of C4H9Cl has the lowest boiling point?
Which isomer of C4H9Cl has the lowest boiling point?
Show Hint
Branched isomers generally have lower boiling points compared to their straight-chain counterparts due to weaker van der Waals forces arising from their reduced surface area.

Solution and Explanation
The isomer of C4H9Cl with the lowest boiling point is tert-butyl chloride C4H9Cl. This is because branching reduces the surface area of the molecule, leading to weaker intermolecular forces (van der Waals forces) and consequently a lower boiling point compared to the straight-chain isomer.
