Question

Among NaF, RbF, KF & CsF most ionic and

strongly ionic are respectively

1) CsF, CsF 2) CsF, NaF

3) NaF, NaF 4) NaF, CsF​

Answer 1

Answer:

Answer:CsF,NaF

CsF is more ionic compound because the compound is formed by large cation( Cs) and small anion( F)

NaF is strong ionic because the electronegativity difference is more than 2.1 ,then it is ionic

or else NaF is more ionic based on lattice energy .NaF is having more Lattice energy
