I am 100% sure it will be KBr it is in my notes.

I chose the same in exam

@Karan_2020
I don't know if this is right, but still hear me out. We know AgBr shows both and we have KBr and CsBr here now Ag is in period 5 and K in period 4 now side of Ag will be small due to poor shielding of d orbital and hence will have radius quite close to K. Hence KBr seems correct.

This is what i found

well! :joy:

Offcource in these options it will be kbr

A is the only option i feel

Even i think it should be KBr , still i shared what i found :slight_smile:

Why didn't you voted shwetanshu_2018

I think KBr
