Vedclass · Answer

(D) The correct answer is $(d)$.$1$. Chloroform $(CHCl_3)$ has a density of approximately $1.48 \ g/cm^3$,which is greater than water $(1 \ g/cm^3)$,so it is heavier than water.$2$. The nucleophilicity of halide ions in polar protic solvents follows the order $I^{-} > Br^{-} > Cl^{-} > F^{-}$. Thus,$Br^{-}$ is a weaker nucleophile than $I^{-}$. This statement is false.$3$. Vinyl chloride $(CH_2=CH-Cl)$ is less reactive than allyl chloride $(CH_2=CH-CH_2Cl)$ towards nucleophilic substitution because the $C-Cl$ bond in vinyl chloride acquires partial double bond character due to resonance,making it stronger and harder to break. This statement is also false.Since both $(b)$ and $(c)$ are false,the correct option is $(d)$.
