A

increases with increasing thermal stability of the hydride

B

increases with decreasing thermal stability of the hydride

C

is no related to the thermal stability of the hydride

D

increases with increasing volatility of the hydride

Text Solution

Verified by Experts

The correct Answer is:
B
Increasing order of acidic strength (and decreasing order of thermal stability) is
`H_2O lt H_2S lt H_2Se lt H_2Te`
