Question

Match the following and identify the correct option.

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

• A. (iii) (iv) (ii) (i)
• B. (i) (iii) (ii) (iv)
• C. (iii) (i) (ii) (iv)
• D. (iii) (ii) (i) (iv)

Answer 1

The correct option is C (iii) (i) (ii) (iv)

$\Rightarrow CO\left(g\right)+H_2\left(g\right)=\text{Water gas or synthesis gas}$
$\Rightarrow \text{Temporary hardness of water is due to bicarbonates of}C{a}^{2+}\text{\&}M{g}^{2+}$
$\Rightarrow B_2{H}_6\text{is a electron deficient compound due to presence of banana bond.}$
$\Rightarrow H_2{O}_2\text{open book like structure which is non-planar}$
