Vedclass · Answer

(B) gem-dihalide is a compound where two halogen atoms are attached to the same carbon atom. $R-CH(X)_2 + 2KOH(aq) \rightarrow R-CH(OH)_2 + 2KX$. Since a geminal diol (having two $-OH$ groups on the same carbon) is unstable,it loses a water molecule to form a carbonyl compound. If the gem-dihalide is a terminal one $(R-CHX_2)$,it forms an aldehyde. If the gem-dihalide is a non-terminal one $(R-C(X)_2-R')$,it forms a ketone. However,in the context of general chemistry questions,the hydrolysis of gem-dihalides is typically associated with the formation of carbonyl compounds (aldehydes or ketones). Given the options,if we consider the simplest gem-dihalide like $CH_3-CHCl_2$ ($1$,$1$-dichloroethane),it yields acetaldehyde. Thus,$B$ is the most specific correct answer.
