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 thesewide variations in b.p. ?A. The molecular mass increases from water (18) to methanol (32) to diethyl ether (74)B. The extent of H-bonding decreases from water to methanol while it is absent in etherC. The extent of intramolecular H-bonding decreases from ether to methanol to waterD. The density of water is 1.00 g `ml^(-1)` methanol `0.7914 g ml^(-1)`- and that of diethyl ether is `0.7137 g ml^(-1)` |
