Vedclass · Answer

(A) Step $1$: Dimethyl ketone is acetone,$CH_3COCH_3$. Reaction with $CH_3MgCl$ followed by $H_2O$ (Grignard reaction) yields $tert$-butyl alcohol,$X = (CH_3)_3COH$.Step $2$: Reaction of $X$ with $Na$ gives the alkoxide $(CH_3)_3CONa$. Subsequent reaction with $CH_3Br$ (Williamson ether synthesis) yields $tert$-butyl methyl ether,$Y = (CH_3)_3COCH_3$.Step $3$: In $Y$,the structure is $(CH_3)_3C-O-CH_3$. The carbons are: three methyl carbons attached to the central carbon,the central quaternary carbon,and the methyl carbon attached to oxygen. All $5$ carbons are $sp^3$ hybridized.

Consider the reaction sequence:
Dimethyl ketone $\xrightarrow[(ii) H_2O]{(i) CH_3MgCl} X$ $\xrightarrow[(ii) CH_3Br]{(i) Na} Y$
How many $sp^3$ carbons are present in $Y$?
