Vedclass · Answer

(D) The reaction of $but-1-ene$ $(CH_3CH_2CH=CH_2)$ with various reagents is analyzed as follows:$1$. $Br_2 / CCl_4$: Forms $1,2-dibromobutane$. The carbon at $C-2$ becomes chiral,resulting in a racemic mixture (optically inactive).$2$. $HBr$: Forms $2-bromobutane$. The carbon at $C-2$ is chiral,resulting in a racemic mixture (optically inactive).$3$. $H_2O / H^{+}$: Forms $butan-2-ol$. The carbon at $C-2$ is chiral,resulting in a racemic mixture (optically inactive).$4$. $(BH_3)_2 / H_2O_2, OH^{-}$: Forms $butan-1-ol$. The product $CH_3CH_2CH_2CH_2OH$ does not contain any chiral carbon atom,making it inherently optically inactive.While options $A$,$B$,and $C$ produce racemic mixtures (which are optically inactive),option $D$ produces a molecule that is achiral by structure. In standard competitive chemistry contexts,the formation of an achiral molecule is the definitive answer for 'optically inactive product'.

Which of the following reagents reacts with $but-1-ene$ to give an optically inactive product?
