Assertion: The boiling point of diethyl ether is Much less than that of ethanol. Reason : In ethanol, the molecules are associated by the formation of intermolecular hydrogen bonding whereas in diethyl ether, it is not possible .

Convert the following : Ethanol into diethyl ether

Boiling point of ethanol (C_2H_5OH) is higher than dimethyl ether (CH_3— O— CH_3) . Explain.

Assertion : P_4 is more reactive than N_2 . Reason: P-P single bond in P_4 is much weaker than N-=N in N_2 molecule.

Stability of a crystal is reflected in the magnitude of its melting points'. Comment. Collect melting points of solid water.ethyl alcohol, diethyl ether and methane from a data book. What can you say about the intermolecular forces between these molecules?

Give reasons for the following: i) Butan -1-ol has a higher boiling point than diethyl ether. ii) (H_(3)C)_(3) C-O - CH_(3) on reacting with HI give (CH_(3))_(3) C- I and CH_(3)-OH as the main products and not (CH_(3))_(3)C-OH and CH_(3)-I .
