How can propan$-2-$one be converted to tertiary butyl alcohol?
(N/A) Propan$-2-$one $(CH_3COCH_3)$ reacts with a Grignard reagent,methyl magnesium halide ($CH_3MgX$,where $X = Cl, Br, I$),in the presence of dry ether to form an addition product.
This addition product is then subjected to acid hydrolysis $(H^+/H_2O)$ to yield tertiary butyl alcohol ($2$-methylpropan$-2$-ol).
The reaction is as follows:
$CH_3COCH_3 + CH_3MgX \xrightarrow{\text{dry ether}} (CH_3)_3COMgX$
$(CH_3)_3COMgX + H_2O \xrightarrow{H^+} (CH_3)_3COH + Mg(OH)X$
This addition product is then subjected to acid hydrolysis $(H^+/H_2O)$ to yield tertiary butyl alcohol ($2$-methylpropan$-2$-ol).
The reaction is as follows:
$CH_3COCH_3 + CH_3MgX \xrightarrow{\text{dry ether}} (CH_3)_3COMgX$
$(CH_3)_3COMgX + H_2O \xrightarrow{H^+} (CH_3)_3COH + Mg(OH)X$

View SolutionGiven below are two statements:
Statement $I:$ The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions.
Statement $II:$ The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of $H$-bonding.
