INote for OP
+solved @user1 @user2...
CA.
acetone pretty polar whereas chcl3 is very less polar so +ve deviation
B.
benzene is non polar whereas methanol has h bonding so +ve deviation
C.
hno3 has intramolecular h bonding whereas with hno3 it forms intermolecular h bonds which are weaker so +ve deviation
D. h bonding b/w h+ of hcl and O of h2o so -ve deviation
acetone pretty polar whereas chcl3 is very less polar so +ve deviation
B.
benzene is non polar whereas methanol has h bonding so +ve deviation
C.
hno3 has intramolecular h bonding whereas with hno3 it forms intermolecular h bonds which are weaker so +ve deviation
D. h bonding b/w h+ of hcl and O of h2o so -ve deviation
Chowever the ques is single correct
Cso where am i wrong
RChloroform and acetone shows negative deviation
RAnd Any mineral acid with water also shows negative deviation in general
RH of CHCl3 is polar enough to form hydrogen bonding with O of acetone
Cok makes sense
Clogic theek hai ?
Calso wha bout B and C
RLogic is simple na.. like for eg HNO3 and H20 yaha to bohot bdhia h-bonding hogi intermolecular forces kafi badh jayege unlike molecules (HNO3 and H20) ke beech me so it will show negative deviation
Cintramolecular H bonds are stronger tho
RBut that doesnt prevent it from getting volatile
Csamjha nahi
Chow does volatility matter
RSee intermolecular forces zyada hoge to hamara mixture less volatile ban jayega to less vapour p i.e it is showing negative deviation
RAnd that benzene and methanol one.. tbh i dont remember the exact reason uska positive deviation ka
Cbenzene just gets in the way of h bonding
RYeah makes sense Methanol-Methanol ka to strong H bonding hota hai warna
Cthats exactly my point
Cintramolecular forces are stronger
RBut in the pure HNO3 the H bonding is not significant right?
RThe h2o hno3 h bonding is way stronger
Cwhy

Coh nice idea
Chmm
Ci read the theory once again and remembered ion dipole interactions are stronger than h bonds
Cin C option h2o (dipole) interacts with polar acetone so -ve deviation
