Vedclass · Answer

(C) Let us analyze each statement:$(i)$ tert-butyl chloride is a tertiary alkyl halide. It undergoes hydrolysis via the $S_N1$ mechanism,which is favored by the formation of a stable tertiary carbocation. Thus,it is easily hydrolysed. This statement is correct.$(ii)$ In the Victor-Meyer test,primary alcohols give red,secondary alcohols give blue,and tertiary alcohols give no colour. This statement is correct.$(iii)$ The structure shown is $CH_3-CH_2-CH(CH_3)-CH(OH)-CH_3$. The longest chain has $5$ carbons. Numbering from the right gives the hydroxyl group at position $2$ and the methyl group at position $3$. The name is $3-$methylpentan$-2-$ol. This statement is correct.$(iv)$ Alcohols react with Grignard reagents $(R'MgX)$ to form alkanes $(R'H)$,not $H_2$ gas. For example,$ROH + R'MgX \rightarrow RH + R'H + Mg(OH)X$. This statement is incorrect.Since statements $(i)$,$(ii)$,and $(iii)$ are correct,the correct option is $(C)$.
