Pentan-1-ol, butan-2-ol, butan-1-ol, propan-1-ol

Pentan-1-ol, butan-1-ol, butan-2-ol, propan-1-ol

Text Solution

Verified by Experts

The correct Answer is:

The boiling points of alcohols increase with increase in molecular mass. Further, among isomeric alcohols, boiling points follow the order :
`1^(@)` alcohols `gt 2^(@)` alcohols `gt3^(@)` alcohols
Keeping these facts in view, the b.ps of the given alcohols follows the order :
Propan-1-ol`lt` butan-2-ol `lt` butan-1-ol `lt` pentan-1-ol.
