QJEEM23Chc3d5: JEE Main 2023 Chemistry - Class 11 JEEM23Chc3d5 Solution: Which hydride among the following is less stable?
Which hydride among the following is less stable?
Multiple Choice Options
- A NH
- B HF
- C LiH
- D BeH
Step-by-Step Verified Solution
The stability of hydrides depends on their bonding and the electronegativity difference between the elements. The greater the electronegativity difference, the more stable the hydride. Based on this, the order of stability of the given hydrides is:
HF > NH > LiH > BeH
Therefore, the less stable hydride among the given options is BeH .
