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 molecule of $H_2O_2$ lie in the same plane. (iii) Hydrogen peroxide is neutral like water. (iv) $H_2O_2$ can be prepared from $BaO_2$ but not from $MnO_2$ and $PbO_2$

• A. (i) and (iv) - true, (ii) and (iii) - false
• B. (i) and (ii) - true, (iii) and (iv) - false
• C. (iii) and (iv) - true, (i) and (ii) - false

(i) and (iv) - true, (ii) and (iii) - false

Answer 2

All four atoms of $H_2O_2$ do not lie in same plane. Hydrogen peroxide is slightly acidic in nature.
