Question

Why acidic character increases form H2O to H2 Te

Answer 1

QUESTION -

Why acidic character increases form H2O to H2 TE?

ANSWER -

The increase in acidic character from H2O to H2Te can be explained on the basis of size of the central atom.

As the size of central atom increases in the order O < S < Se < Te, the distances between the central atom and hydrogen also increases. As a result of increase in bond lengths, the bond dissociation enthalpy decreases and bond cleavage becomes more and more easy. Therefore, the acidic strength of the hydrides increases down the group.

Answer 2

Answer:

$\mathbb{\huge{\underline{\underline{\red{ANSWER}}}}}$

Acidic character increases from H2O to H2Te because of the decrease in bond dissosiation enthalpy H+ can be released easily, so more is the acidic character
