Chemistry

Glucose,because it is non electrolyte and can't be dissociated into ions, therefore its vantoff factor(i)becomes 1, in other examples i is more then 1, and for equimolar solution V.P is inveresly proportional to i, from here we can conclude glucose will have higher Vapour pressure.

Correct ans is A(glucose) B'coz its a non volatile compound so it will not dissociate Into ions so its vontoff factor. Will be 1 Where as other will dissociate into ions For reference: k2so4 vontoff factor is 1 K4(Fe(CN)6) is 5 Nacl is 2

4 is answer

Sorry it is 1

It's 1 st

For higher vapour pressure boiling point should be low So b.p depends on vont Hoff factor Jiska vont Hoff factor kam uska b.p kam and then vapour pressure jyada Here vont Hoff factor value of glucose is one which is least So it's vapour pressure is highest Option 1 is correct.
