Step-by-step explanation
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.
