Question

If the boiling point of ethanol (molecular weight $-46$) is ${78}^{o}C$ , what is the boiling point of diethyl ether (molecular weight=$74$)?

• A. ${100}^{o}C$
• B. ${70}^{o}C$
• C. ${86}^{o}C$
• D. ${34}^{o}C$

Answer 1

The correct option is D ${34}^{o}C$

Boiling point of ethonol is ${78}^{\circ }C$ B.P of ethanol is higher than diethylether because of the presence of inter molecular hydrogen bonding in ethanol. B.P of ether < ethanol.
