$n$-Butyl alcohol

Vedclass · Answer

(A) The boiling point of isomeric alcohols depends on the surface area of the molecule. As the branching in the carbon chain increases,the surface area decreases,which leads to weaker van der Waals forces of attraction between the molecules. Therefore,the boiling point decreases with an increase in branching. Among the given isomers,$n$-Butyl alcohol is a straight-chain alcohol with no branching,while the others have varying degrees of branching. Thus,$n$-Butyl alcohol has the highest boiling point.
