DifficultMatch the reactions given in Column-$I$ with their products in Column-$II$.
Column-$I$ (Reactant) Column-$II$ (Product) $A$. $RCH_2OH \xrightarrow[(ii) H_3O^{+}]{(i) NaOH, KMnO_4} ?$ $i$. $C_6H_5COOH + C_2H_5OH$ $B$. $CH_3(CH_2)_8CH_2OH \xrightarrow{Jones reagent} ?$ $ii$. $RCOOH$ $C$. $RCONH_2 \xrightarrow{H_3O^{+}, \Delta} ?$ $iii$. $CH_3(CH_2)_8COOH$ $D$. $C_6H_5COOEt \xrightarrow{H_3O^{+}} ?$ $iv$. $RCOOH + NH_3$
| Column-$I$ (Reactant) | Column-$II$ (Product) |
| $A$. $RCH_2OH \xrightarrow[(ii) H_3O^{+}]{(i) NaOH, KMnO_4} ?$ | $i$. $C_6H_5COOH + C_2H_5OH$ |
| $B$. $CH_3(CH_2)_8CH_2OH \xrightarrow{Jones reagent} ?$ | $ii$. $RCOOH$ |
| $C$. $RCONH_2 \xrightarrow{H_3O^{+}, \Delta} ?$ | $iii$. $CH_3(CH_2)_8COOH$ |
| $D$. $C_6H_5COOEt \xrightarrow{H_3O^{+}} ?$ | $iv$. $RCOOH + NH_3$ |
(A-II, B-III, C-IV, D-I) The correct matches are:
$A \rightarrow ii$: Primary alcohols $(RCH_2OH)$ are oxidized to carboxylic acids $(RCOOH)$ using strong oxidizing agents like $KMnO_4$.
$B \rightarrow iii$: Primary alcohols are oxidized to carboxylic acids using Jones reagent $(CrO_3/H_2SO_4)$.
$C \rightarrow iv$: Amides $(RCONH_2)$ undergo acid-catalyzed hydrolysis to yield carboxylic acids $(RCOOH)$ and ammonia $(NH_3)$.
$D \rightarrow i$: Esters $(C_6H_5COOEt)$ undergo acid-catalyzed hydrolysis to yield the corresponding carboxylic acid $(C_6H_5COOH)$ and alcohol $(C_2H_5OH)$.
Therefore,the correct sequence is $A-ii, B-iii, C-iv, D-i$.
