Question

Which among the following has the highest boiling point?

Options

• C₂H₅N(CH₃)₂

• n-C₄H₉NH₂

• (C₂H₅)₂NH

• C₂H₅CH(CH₃)₂

Answer 1

n-C₄H₉NH₂

Explanation:

The boiling point of amines is higher than that of alkanes for compounds of comparable molar mass.

Primary amine > secondary amine > tertiary amine is the observed order of boiling points of isomeric amines.
