Question

Match the following and identify the correct option.

(a) $CO\left(g\right)+H_2\left(g\right)$	(i)$Mg{\left(HC{O}_3\right)}_2+Ca{\left(HC{O}_3\right)}_2$
(b) Temporary hardness of water	(ii) An electron deficient hydride
(c) $B_2{H}_6$	(iii) Synthesis gas
(d) $H_2{O}_2$	(iv) Non - planar structure

• A. (a) $\to$(iii); (b) $\to$(iv); (c) $\to$(ii); (d) $\to$(i)
• B. (a) $\to$(i); (b) $\to$(iii); (c) $\to$(ii); (d) $\to$(iv)
• C. (a) $\to$(iii); (b) $\to$(i); (c) $\to$(ii); (d) $\to$(iv)
• D. (a) $\to$(iii); (b) $\to$(ii); (c) $\to$(i); (d) $\to$(iv);

Answer 1

The correct option is C (a) $\to$(iii); (b) $\to$(i); (c) $\to$(ii); (d) $\to$(iv)

$CO+H_2\to \text{Syn gas}$
Temporary hardness $\Rightarrow$ due to bicarbonates of $M{g}^{+2}$ and ${Ca}^{+2}$$B_2{H}_6\to e^{-}$ deficient
$H_2{O}_2\to$ Half open book $\Rightarrow$Non-planar structure

Hence, (c) is the correct option.
