Vedclass · Answer

(A) The transformation involves the anti-Markovnikov hydration of an alkene followed by the oxidation of the resulting primary alcohol to an aldehyde.$1$. Hydroboration-oxidation: The reaction of $Cyclohexyl-CH_2-CH=CH_2$ with $(i) BH_3$ followed by $(ii) H_2O_2 / \stackrel{\ominus}{O}H$ yields the primary alcohol,$Cyclohexyl-CH_2-CH_2-CH_2OH$.$2$. Oxidation: The primary alcohol is then oxidized to an aldehyde using a mild oxidizing agent like $PCC$ (Pyridinium chlorochromate),which stops the oxidation at the aldehyde stage.Therefore,the correct sequence of reagents is $(i) BH_3, (ii) H_2O_2 / \stackrel{\ominus}{O}H, (iii) PCC$.

List-$I$ (Reagents)	List-$II$ (Reaction Name)
$A$. $H_2, Pd-BaSO_4$	$I$. Etard Reaction
$B$. $SnCl_2, HCl$	$II$. Rosenmund Reduction
$C$. $CrO_2Cl_2, CS_2$	$III$. Gatterman-Koch Reaction
$D$. $CO, HCl, \text{Anhyd. } AlCl_3$	$IV$. Stephen Reaction
