Chemical Properties of Elements -
Nature of Hydrides
Hydrides are basically the compounds with hydrogen atom or atoms and some other element.
In a period, the nature of hydrides changes from basic to acidic in moving from left to right.
|
NH3 |
H2O |
HF |
|
Weak base |
Neutral |
Weak acid |
In a group, the acidic nature of hydrides increases in moving from top to bottom. Thus,
HI > HBr > HCl > HF
-
Water is a neutral hydride. The bonds in water (hydroxide ion bound to a hydrogen ion) are stronger than the sulfide and hydrogen ion bonds. An acid always gives up a hydrogen ion (or multiple H+ions). H2S is acidic while H2O is neutral.
Therefore, Option(2) is correct
