$N$-Methylpyrrolidine and Piperidine

Vedclass · Answer

(D) The boiling point $(B.P.)$ of a compound depends on the strength of intermolecular forces. $1.$ In option $(A)$,cyclopropanol has intermolecular $H$-bonding,while oxetane does not,so cyclopropanol has a higher $B.P.$ $2.$ In option $(B)$,acetone has dipole-dipole interactions,while propene has only weak London dispersion forces,so acetone has a higher $B.P.$ $3.$ In option $(C)$,ethane$-1,2-$diol $(HO-CH_2-CH_2-OH)$ has two $-OH$ groups allowing extensive intermolecular $H$-bonding,whereas propan$-1-$ol $(CH_3-CH_2-CH_2-OH)$ has only one $-OH$ group. Thus,the first compound has a higher $B.P.$ $4.$ In option $(D)$,$N$-methylpyrrolidine is a tertiary amine with no $H$-bonding,while piperidine is a secondary amine capable of intermolecular $H$-bonding. Therefore,the second compound (piperidine) has a higher $B.P.$ than the first compound.

In the given pair of compounds,in which pair does the second compound have a higher boiling point than the first compound?
