To determine which compound has the highest boiling point, we need to consider the intermolecular forces present in each compound. The strength of the intermolecular forces directly affects the boiling point.
Among the given compounds, here is the order of increasing intermolecular forces:
2-methylpropan-2-ol (b) - This compound has hydrogen bonding between the -OH groups and London dispersion forces due to the carbon chain.
butan-2-ol (c) - This compound has hydrogen bonding between the -OH group and London dispersion forces due to the carbon chain.
2-methylpropan-1-ol (a) - This compound has hydrogen bonding between the -OH group and London dispersion forces due to the carbon chain.
butan-1-ol (d) - This compound has hydrogen bonding between the -OH group and London dispersion forces due to the carbon chain.
Based on the order of increasing intermolecular forces, we can conclude that the compound with the highest boiling point is butan-1-ol (d).
Some isomers of C4H10O are:
CH3 - CH (CH3) - CH2 - OH
2-methylpropan-1-ol
CH3 - CH ((CH3)(OH)) - CH2 - OH
2-methylpropan-2-ol
butan-1-ol
butan-2-ol
Which of the above compounds has the highest boiling point?

C4H10O has four different isomers: 2-methylpropan-1-ol, 2-methylpropan-2-ol, butan-1-ol, and butan-2-ol. So which one has the highest boiling point?
Apologies for the confusion in my previous response. Let's re-evaluate the given compounds and their boiling points to determine which one has the highest boiling point.
The boiling points of the compounds are as follows:
2-methylpropan-1-ol: 107.9°C
2-methylpropan-2-ol: 82.5°C
butan-1-ol: 118.1°C
butan-2-ol: 99.5°C
Based on the boiling points provided, we can conclude that butan-1-ol (c) has the highest boiling point of 118.1°C.
The boiling points of the compounds are as follows:
2-methylpropan-1-ol: 107.9°C
2-methylpropan-2-ol: 82.5°C
butan-1-ol: 118.1°C
butan-2-ol: 99.5°C
Based on the boiling points provided, we can conclude that butan-1-ol (c) has the highest boiling point of 118.1°C.
d) butan-1-ol ?
Apologies for the mistake. Yes, you are correct. Among the given compounds, butan-1-ol (d) has the highest boiling point of 118.1°C. Thank you for pointing that out.
