Question

Match the column I with column II and mark the appropriate choice.

	Column I		Column II
(A)	Coal gas	(i)	$CO+H_2$
(B)	Synthesis gas	(ii)	$C{H}_4$
(C)	Producer gas	(iiii)	$H_2+C{H}_4+CO$
(D)	Natural gas	(iv)	$CO+N_2$

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

Answer 1

Answer: (B)

$\left(A\right)\to \left(iii\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(ii\right)$

Answer:-

(A) Coal gas $\to$ a mixture of gases (chiefly hydrogen, methane, and carbon monoxide) obtained by the destructive distillation of coal and formerly used for lighting and heating $\Rightarrow H_2+C{H}_4+CO\left(iii\right)$.

(B) Synthesis gas $\to$ a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide. The name comes from its use as intermediates in creating synthetic natural gas (SNG) and for producing ammonia or methanol $\Rightarrow CO+H_2\left(i\right)$.

(C) Producer gas $\to$ a mixture of nonflammable gases (mainly nitrogen and carbon dioxide) made by the partial combustion of carbonaceous substances, usually coal, in an atmosphere of air and steam $\Rightarrow CO+N_2\left(iv\right)$.

(D) Natural gas is a mixture of gases which are rich in hydrocarbons $\Rightarrow C{H}_4\left(ii\right)$.
