Vedclass · Answer

(C) gem-dichloride (geminal dichloride) has two chlorine atoms attached to the same carbon atom.$1$. $CH_3CHO + PCl_5 \rightarrow CH_3CHCl_2 + POCl_3$ (This forms $1,1$-dichloroethane,which is a gem-dichloride).$2$. $CH_3COCH_3 + PCl_5 \rightarrow CH_3CCl_2CH_3 + POCl_3$ (This forms $2,2$-dichloropropane,which is a gem-dichloride).$3$. $CH_2 = CH_2 + Cl_2 \rightarrow ClCH_2-CH_2Cl$ (This forms $1,2$-dichloroethane,which is a vicinal dichloride,not a gem-dichloride).$4$. $CH_2 = CHCl + HCl \rightarrow CH_3CHCl_2$ (This follows Markovnikov's rule to form $1,1$-dichloroethane,which is a gem-dichloride).Therefore,the reaction that does not form a gem-dichloride is $CH_2 = CH_2$ and $Cl_2$.

$A$ gem-dichloride is formed in the reaction except:
