Question

Some organic compounds are given in List I and their uses in List II. Choose the correct matching.

List I	List II
$\left(A\right)$ Triiodomethane	$\left(i\right)$ Solvent for alkaloids
$\left(B\right)$ $p,p^{{}^{\prime }}$-dichlorodipheny 1-trichloroethane	Propellent in aerosols
$\left(C\right)$ Trichloromethane	$\left(iii\right)$ Antiseptic
$\left(D\right)$ Dichloromethane	$\left(iv\right)$ Insecticide

• A. $\left(A\right)-\left(ii\right),\left(B\right)-\left(iv\right),\left(C\right)-\left(i\right),\left(D\right)-\left(iii\right)$
• B. $\left(A\right)-\left(iii\right),\left(B\right)-\left(iv\right),\left(C\right)-\left(i\right),\left(D\right)-\left(ii\right)$
• C. $\left(A\right)-\left(ii\right),\left(B\right)-\left(i\right),\left(C\right)-\left(iv\right),\left(D\right)-\left(iii\right)$
• D. $\left(A\right)-\left(iii\right),\left(B\right)-\left(i\right),\left(C\right)-\left(iv\right),\left(D\right)-\left(ii\right)$
• E. $\left(A\right)-\left(i\right),\left(B\right)-\left(iii\right),\left(C\right)-\left(ii\right),\left(D\right)-\left(iv\right)$

Answer 1

The correct option is B $\left(A\right)-\left(iii\right),\left(B\right)-\left(iv\right),\left(C\right)-\left(i\right),\left(D\right)-\left(ii\right)$

$\left(A\right)$ Triiodomethane $\to$ $\left(iii\right)$ used as an antiseptic.
$\left(B\right)$ $p,p^{{}^{\prime }}$-dichlorodiphenyltrichloroethane (also called DDT) $\to$ $\left(iv\right)$ used as an insecticide.
$\left(C\right)$ Trichloromethane $\left(CH{Cl}_3\right)\to$ $\left(i\right)$ used as a solvent for alkaloidds.
$\left(D\right)$ Dichloromethane $\left(C{H}_2{Cl}_2\right)\to$ $\left(ii\right)$ used as propellent in aerosols.
