| I. Nature of the oxide |
| II. Electropositive character |
| III. Combination with alkali metals |
| IV. Atomicity |
A) I and III
B) I and II
C) III and IV
D) Only II
Correct Answer: B
Solution :
Hydrogen forms a neutral oxide, i.e. \[{{C}_{p}}=5.006+0.0026T\] (water) whereas the oxides of halogens are acidic. Hydrogen shows electropositive nature also whereas halogens are mostly electronegative in nature.
