Question

In which of the properties listed below, hydrogen does not show similarity with halogens?
(i) Nature of the oxide
(ii) Electropositive character
(iii) Combination with alkali metals
(iv) Atomicity

• A. (i) and (ii) only
• B. (iii) and (iv) only
• C. (ii) only
• D. (i) and (iii) only

Answer 1

Answer: (A)

Hydrogen forms a neutral oxide, i.e., $H_{2}O$ (water) while the oxides of halogens are acidic. Hydrogen shows electropositive nature also while halogens are mostly electronegative in nature.
