Vedclass · Answer

(D) The boiling point $(B.P.)$ depends on the strength and extent of intermolecular forces,primarily hydrogen bonding and molecular weight/surface area.$(w)$ is cyclopentanol,which forms strong intermolecular $H$-bonding.$(z)$ is piperidine,which also forms $H$-bonding,but $N-H \dots N$ bonds are weaker than $O-H \dots O$ bonds.$(x)$ is tetrahydropyran (an ether) and $(y)$ is $N$-methylpyrrolidine (a tertiary amine),which do not form $H$-bonds with themselves.Comparing molecular weights and polarities,the order is: $(w) > (z) > (x) > (y)$.Therefore,the correct option is $(D)$.

Arrange the following $(w, x, y, z)$ in decreasing order of their boiling points.
