Vedclass · Answer

(A) The reaction of $D$-glucose with dilute alkali is known as the Lobry de Bruyn-van Ekenstein transformation. This process involves the formation of an enediol intermediate. During the formation of the enediol,the $C_2$ carbon atom changes its hybridization from $sp^3$ to $sp^2$. This intermediate allows for the interconversion between glucose,mannose,and fructose. Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion : Treatment of $D$-glucose with dilute alkali affords an equilibrium mixture consisting of $D$-mannose,$D$-fructose and starting substance $D$-glucose.
Reason : The reaction involves an intermediate in which hybridization of $C_2$ changes from $sp^3$ to $sp^2$.
