Fajan's Rules
Why is the answer not BaCl2(more +ve charge means more covalent character right?)

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.I'm not sure but this is what i got
n size of Ag+<Ba2+ so if cation's size increases the covalent character decreases
and hence ionic chr increases
is K+ smaller than Ag+
considerably
look at the atomic numbers
19 and 47
then shouldn't KCl be the most ionic
yeah but the question asked least ionic
Ba has a +2 charge but is larger than Ag
for least ionic, you need:
* less charge on the cation and anion
* bigger cation
* smaller anion
if the answer's AgCl then charge is the dominating factor rather than size
never trust AI summaries
charge dominates over size https://old.reddit.com/r/chemhelp/comments/1hi1b9p/question_fajans_rule_priority/ (+ proof by electrostatics in the comments)
google's AI especially is really bad
sorry I meant to type most covalent
I thought according to Fajan's rules, covalent character depends on:
1. Smaller size of cation
2. More Charge of Cation
3. Larger Anion
If a compound has more covalent character then it's ionic character decreases
kindly excuse me if I botched up the concept
More zeff, More polarizing power, more covalent character, less ionic character
thanks
the SCLA trick works always.
S for size, C for charge, A for atomicity but what about L
Isn't it because Ag+ is pseudo inert configuration?
idk but ig Lattice energy
this is it doston. please close it out :) @Percy
Thanks for the detailed response!
Cool notes.
