Vedclass · Answer

(A) The reactivity of alcohols towards $Na$ metal depends on the acidity of the alcohol,as the reaction involves the release of $H^+$ ions to form alkoxides $(R-O^-Na^+)$.
The acidity of alcohols decreases as the number of alkyl groups attached to the carbon bearing the $-OH$ group increases due to the $+I$ effect of alkyl groups,which destabilizes the alkoxide ion.
Therefore,the order of acidity is: $	ext{Primary} > 	ext{Secondary} > 	ext{Tertiary}$.
Consequently,the order of reactivity towards $Na$ metal is: $	ext{Primary} > 	ext{Secondary} > 	ext{Tertiary}$.
