Cold $KMnO_4, RCO_3H / H_3O^{\oplus}$

(B) $1$. $cis-3-hexene$ undergoes $syn-addition$ of $OH$ groups using cold alkaline $KMnO_4$ or $OsO_4$ to form $meso-3,4-hexanediol$.$2$. $trans-3-hexene$ undergoes $anti-addition$ of $OH$ groups using $RCO_3H$ followed by acid-catalyzed hydrolysis $(H_3O^{\oplus})$ to form $meso-3,4-hexanediol$.$3$. Therefore,$(a)$ is cold $KMnO_4$ (or $OsO_4$) and $(b)$ is $RCO_3H / H_3O^{\oplus}$.
