AgF is ionic , so more soluble

AgCl has covalent character

 

Vander walls forces are max. in AgBr

because larger the size , more are vanderwalls forces

THANK YOU VERY MUCH !

 

 

 

 

The inc. in size for thallium is due to inc. in shielding effect due to inc. in no. of shells.So the effective nuclear charge decreases.This shieiding is more effective than in case of indium and gallium.

 

hello jatinpreet!

I think 'a' and 'b' are correct.

because,

G= H - TS

CLEARLY THE LIQUID PERFUME IS CHANGING TO VAPOUR STATE , SO THE ENTROPY IS +VE (favourable). AS IT IS MIXING WITH AIR , SO S , WILL BE LARGE.SO G WILL BE  -VE. HENCE G<0.
