Question

For each pair of compounds, determine which compound boils at a higher temperature. Give a brief explanation for your predictions.
(i) heptan-1-ol or 3,3-dimethylpentan-1-ol
(ii) pentan-2-one or pentan-2-ol

Accepted Answer

(i) heptan-1-ol, because it has a linear structure.

(ii) pentan-2-ol, because it can form intermolecular hydrogen bonding.

Answer

(i) 3,3-dimethylpentan-1-ol, because it has a branched structure.

(ii) pentan-2-ol, because it can form intermolecular hydrogen bonding.

Answer

(i) heptan-1-ol, because it has more hydroxyl groups.

(ii) pentan-2-one, because it has a carbonyl group which can form strong intermolecular interactions.

Answer

(i) 3,3-dimethylpentan-1-ol, because it has more hydroxyl groups.

pentan-2-one, because it has a higher molecular weight.
