A) \[CsH>RbH>KH>NaH>LiH\]
B) \[KH>NaH>LiH>CsH>RbH\]
C) \[NaH>LiH>KH>RbH>CsH\]
D) \[LiH>NaH>KH>RbH>CsH\]
Correct Answer: D
Solution :
[d] The stability of alkali metal hydrides decreases from \[Li\]to\[Cs\]. It is due to the fact that \[M-H\]bonds become weaker with increase in size of alkali metals as we move down the group from \[Li\]to\[Cs\]. Thus the order of stability of hydrides is \[LiH>NaH>KH>RbH>CsH\]You need to login to perform this action.
