Question

Bond dissociation energy of "E-H" bond of the " $H _2 E$ " hydrides of group $16$ elements (given below), follows order.
A. $O$ B. $S$ C. $Se$ D. $Te$
Choose the correct from the options given below:

• A. $D > C > B > A$
• B. $B > A > C > D$
• C. $A>B>D>C$
• D. $A>B>C>D$

Answer 1

Answer: (D)

$A>B>C>D$

Answer 2

The correct answer is (D) : A>B>C>D
Bond dissociation energy of E-H bond in hydrides of group 16 follows the order
H2​O>H2​S>H2​Se>H2​Te
