$CsF$

Vedclass · Answer

(A) The strength of an ionic bond is determined by the lattice energy,which is inversely proportional to the interionic distance $(r_+ + r_-)$.$CsF$ consists of $Cs^+$ and $F^-$ ions,while $NaCl$ consists of $Na^+$ and $Cl^-$ ions.The ionic radius of $F^-$ is significantly smaller than that of $Cl^-$.Although $Cs^+$ is larger than $Na^+$,the small size of the $F^-$ ion leads to a shorter interionic distance in $CsF$ compared to $NaCl$.Furthermore,the lattice energy is higher for $CsF$ due to the high charge density of the fluoride ion,making the $Cs-F$ bond stronger in terms of lattice stability.
