Question

Match the following and identify the correct option

(a)	$CO\left(g\right)+H_2\left(g\right)$	(i)	$Mg(HC{O}_3{)}_2+Ca(HC{O}_3{)}_2$
(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. $\left(a\right)\to \left(iii\right);\left(b\right)\to \left(iv\right);\left(c\right)\to \left(ii\right);\left(d\right)\to \left(i\right)$
• B. $\left(a\right)\to \left(i\right);\left(b\right)\to \left(iii\right);\left(c\right)\to \left(ii\right);\left(d\right)\to \left(iv\right)$
• C. $\left(a\right)\to \left(iii\right);\left(b\right)\to \left(i\right);\left(c\right)\to \left(ii\right);\left(d\right)\to \left(iv\right)$
• D. $\left(a\right)\to \left(iii\right);\left(b\right)\to \left(ii\right);\left(c\right)\to \left(i\right);\left(d\right)\to \left(iv\right)$

Answer 1

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

A) Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide.

B) Temporary hardness is a type of water hardness caused by the presence of dissolved bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate).

C) $B_2{H}_6$ - Electron deficient hydride.

D) $H_2{O}_2$- Hydrogen peroxide is a nonplanar molecule with (twisted) symmetry. It is non–linear, non–planar molecule with a open book structure.
