Question

Mark the following statements as true or false
(i) Ordinary hydrogen is a mixture of $75$% ortho and $25$% para- forms
(ii) All the four atoms of moleculle of $H_2{O}_2$ lie in the same plane.
(iii) Hydrogen peroxide is neutral like water.
(iv)$H_2{O}_2$ can be prepared from $Ba{O}_2$ but not from $Mn{O}_2$ and $Pb{O}_2$

• A. $\left(i\right)$ and $\left(iv\right)-$ true $\left(ii\right)$ and $\left(iii\right)$ - false
• B. $\left(i\right)$ and $\left(ii\right)-$ true $\left(iv\right)$ and $\left(iii\right)-$ false
• C. $\left(iii\right)$ and $\left(iv\right)-$ true $\left(ii\right)$ and $\left(ii\right)-$ false
• D. $\left(i\right)$ and $\left(iii\right)-$ true $\left(ii\right)$ and $\left(iv\right)-$ false

Answer 1

Answer: (A)

$\left(i\right)$ and $\left(iv\right)-$ true $\left(ii\right)$ and $\left(iii\right)$ - false

All four atoms of $H_2{O}_2$ do not lie in the same plane. one $H$ and $2O$ atoms lie in the same plane. The remaining H atom lies in another plane.

Hydrogen peroxide is slightly acidic in nature. It reacts with bases to form salt.

$H_2{O}_2+N{a}_{2}C{O}_3\to N{a}_2{O}_2+H_{2}O+C{O}_2$
