Vedclass · Answer

(C) $1$. To decolorize aqueous bromine,the compound must contain an unsaturated bond (alkene or alkyne).$2$. To give white fumes of $HCl$ on reaction with $PCl_5$,the compound must contain an alcoholic group $(-OH)$.$3$. Option $C$ $(CH_3CH = CHCH_2CH_2OH)$ contains both a double bond (for bromine decolorization) and an $-OH$ group (for $HCl$ fumes).$4$. The reaction is: $CH_3CH = CHCH_2CH_2OH + PCl_5 \rightarrow CH_3CH = CHCH_2CH_2Cl + HCl + POCl_3$.
