| LIST I Name of reaction |
LIST II Reagent used |
||
|---|---|---|---|
| A. | Hell-Volhard-Zelinsky reaction | I. | $NaOH + {I_2}$ |
| B. | Iodoform reaction | II. | (i) $Cr{O_2}C{l_2},C{S_2}$ (ii) ${H_2}O$ |
| C. | Etard reaction | III. | (i) $B{r_2}$ / red phosphorus (ii) $H_2O$ |
| D. | Gatterman-Koch reaction | IV. | $CO,HCl,$, anhyd. $AlC{l_3}$ |
Choose the correct answer from the options given below:
Solution
<ul>
<li>Hell-Volhard-Zelinsky reaction involves halogenation and is carried out using halogens like bromine along with red phosphorus and water. So, A matches with III.</li><br/>
<li>Iodoform reaction involves the reaction of iodine and sodium hydroxide. So, B matches with I.</li><br/>
<li>Etard reaction involves the oxidation of aromatic aldehydes and is carried out using chromyl chloride ($\mathrm{CrO_2Cl_2}$) and carbon disulfide ($\mathrm{CS_2}$), followed by water. So, C matches with II.</li><br/>
<li>Gatterman-Koch reaction involves the formation of aromatic aldehydes using carbon monoxide, hydrochloric acid, and anhydrous aluminum chloride. So, D matches with IV.</li>
</ul>
<p>So, the correct option is :</p>
<p>Option B<br/><br/>
A-III, B-I, C-II, D-IV</p>
