Current Question (ID: 8688)

Question:

\text{The correct match among the following is -} \text{(a) CO}_{(g)} + \text{H}_2\text{}_{(g)} \quad \text{(i) Mg(HCO}_3\text{)}_2 + \text{Ca(HCO}_3\text{)}_2 \text{(b) Temporary hardness of water} \quad \text{(ii) An electron deficient hydride} \text{(c) B}_2\text{H}_6 \quad \text{(iii) Synthesis gas} \text{(d) H}_2\text{O}_2 \quad \text{(iv) Non-planar structure}

Options:

1. $\text{(a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)}$
2. $\text{(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)}$
3. $\text{(a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)}$
4. $\text{(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)}$

Solution:

$\text{Hint: Synthesis gas is a mixture of CO and H}_2\text{.}$ $\text{As this mixture of CO and H}_2 \text{ is used for the synthesis of methanol and a number of hydrocarbons,}$ $\text{it is also called synthesis gas or 'syngas'.}$ $\text{C}_{(s)} + \text{H}_2\text{O}_{(g)} \rightarrow 2\text{CO}_{(g)} + \text{H}_2\text{}_{(g)}$ $\text{Temporary hardness is due to the presence of magnesium and calcium hydrogen carbonates.}$ $\text{B}_2\text{H}_6 \rightarrow \text{An electron-deficient hydride.}$ $\text{H}_2\text{O}_2 \rightarrow \text{Non-planar structure}$
