Question

Arrange the given compounds in order of
increasing acidic strength;CH4, NH3, H2O, HF.
Give reason for your answer.​

Answer 1

Answer:

CH3 less than NH3 less than H2O less than HF

Explanation:

The electronegativity increases along period and the acidity of the hydrides of the corresponding elements also increases with the increase in eletronegativity of these elements

Answer 2

Given compounds are arranged in increasing acidic strength as $CH_{4}$ < $NH_{3}$ < $H_{2}O$ < HF.

Explanation:

• A strong acid is defined as the acid which tends to dissociate completely when dissolved in water. And, it an acid dissolves partially or if it is not able to dissolve in water then it is known as a weak acid.

• Also, it is known that when we move across a period then there occurs a decrease in size of the atoms and electronegativity of the atoms tend to increase. As, C, N, O, and F are all same period elements.

• And, florine has the highest electronegativitiy and carbon is least electronegative. So, increasing acidic strength of given species is as $CH_{4}$ < $NH_{3}$ < $H_{2}O$ < HF.
