1.	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_(2)O_(2) lie in the same plane. (iii) Hydrogen peroxide is neutral like water. (iv) H_(2)O_(2) can be prepared from BaO_(2) but not from MnO_(2) and PbO_(2)
Answer» (i) and (iv) - true, (II) and (III) - false (i) and (ii) - true, (iii) and (iv) - false (iii) and (iv) - true, (i) and (ii) - false (i) and (iii) - true, (ii) and (iv) - false Solution :All four atoms of `H_(2)O_(2)` do not lie in same plane. Hydrogen peroxide is slightly ACIDIC in NATURE.
