6 The boiling point of butan-1-ol is 118 °C. The boiling point of 2-methylpropan-2-ol is 82 °C.
Why is the boiling point of butan-1-ol higher than that of 2-methylpropan-2-ol?
A butan-1-ol has stronger induced dipole–dipole interactions because it has more electrons
B butan-1-ol has stronger induced dipole–dipole interactions because it has a straight-chain
structure
C butan-1-ol can form hydrogen bonds while 2-methylpropan-2-ol cannot
D butan-1-ol is more stable because it is a primary alcohol
