Which is the correct thermal stability order for H 2 E (E=O, S, Se, Te and Po) ?
Text Solution
Verified by ExpertsThe correct answer is:
D
In oxygen family down the group thermal stability decreses
order of thermal stability
H 2 O > H 2 S > H 2 Se > H 2 T > H 2 Po]
This is because M–H bond dissociation energy decreases down the group with the increase in the size of central atom
