The boiling points of methanol, water and dimethyl ether are respectively `65^@ C, 100^@ C` and `34.5^@ C`. Which of the following best explains these wide variations in b.p. ?

Options

A. The molecular mass increase from water (18) to methanol(32) to diethyl ether(74)
B. The extent of H-bonding decrease from water too methanol while it is absent in ether
C. The extent of intramolecular H-bondin decrease from ether to methanol to water
D. The density of water is `1.00g*mL^(-1)`, methanol `0.7914g*mL^(-1)` and that of diethyl ether is `0.7137g*mL^(-1)`

Answer

B
