c – BaCl2 because it has more charge density per unit volume and therefore by FAJAN’s rule it is most covalent and least ionic

​d) CaCl2
for maximum ionic char there are some conditions
1- low charge
2- large size of cation ans small size of anion

may be wrong answer but remember conditions that i have maentioned above it will be very helpful

Ans is agcl because it has the least covalent character. Cacl2 has the highest covalent character followed by kcl and then bacl2 and then agcl

ALL OTHER COMPOUND ARE SHOWING INERT PAIR EFFECT WHILE AgCl does not show this effect.The ques is also there in my package also and here also ans is given A so you don`t have to worry wrong answer

K,Ca,ba alakli and alkali earth metals ,so these having more capacity to form the ionic bonds,Ag is transition metal so these having least ionic nature

Ag-d block element & rest belongs to s-block(k,Ba,Ca).as we move from left to right in periodic table ionic character decreases , similarly moving from top to bottom it increases ....so out of these Agcl is less ionic (more ionic is Cacl2,Kcl, Bacl2,Agcl).

If the anion in ionic compounds is same, then the compound with highest melting point will have highest ionic character but the  compound having least Melting point would be less ionic compound.                                                                                                                In the question, AgCl  has the least Melting point which is  455 C ,  hence AgCl is the least ionic from the given compunds
Hence answer is AgCl

agcl is least ionic because ag has pseudo noble gas configurtion and it will be the  dominating factor over size and charge according to fazan’s rule
