Solution

## The correct option is D $$(A) \rightarrow (iii), (B) \rightarrow (i), (C) \rightarrow (iv), (D) \rightarrow (ii)$$Answer:-(A) Coal gas $$\rightarrow$$ a mixture of gases (chiefly hydrogen, methane, and carbon monoxide) obtained by the destructive distillation of coal and formerly used for lighting and heating $$\Rightarrow \; H_2 + CH_4 + CO \; (iii)$$.(B) Synthesis gas $$\rightarrow$$ 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 $$\Rightarrow \; CO + H_2 \;(i)$$.(C) Producer gas $$\rightarrow$$ 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 $$\Rightarrow \; CO + N_2 \; (iv)$$.(D) Natural gas is a mixture of gases which are rich in hydrocarbons $$\Rightarrow \; CH_4 \; (ii)$$.Chemistry
