उत्तर
\[\ce{\underset{Propanol}{CH3CH2CH2OH} + SOCl2 -> CH3CH2CH2C + SO2 + HCl}\]
\[\ce{2CH3CH2CH2OH + \underset{(Metal)}{2Na} -> 2CH3CH2CH2\overset{-}{O}N\overset{+}{a} + H2}\]
\[\ce{\underset{1-Chloropropane}{CH3CH2CH2Cl} + \underset{Sodium propoxide}{CH3CH2CH2\overset{-}{O}}N\overset{+}{a} -> \underset{Propoxypropane}{(CH3CH2CH2)2O}}\]
Mechanism: SN2 attack of propoxide on the halide.
