The most stable compound is
The most stable compound is
Options
- ALiF
- BLiCl
- CLiBr
- DLiI
Correct answer
A. LiF
Step-by-step solution
The electronegativity of halogen is as :
(\mathrm{F} \gt \mathrm{Cl} \gt \mathrm{Br} \gt )
Among alkali metals the electropositive character increases as :
(\mathrm{Li} \lt \mathrm{Na} \lt \mathrm{K} \lt \mathrm{Rb} \lt \mathrm{Cs})
Hence, LiF is the most stable compound.
