Text Solution

Verified by Experts

The correct Answer is:
`(a) rarr p,r,s; (b) rarr p,q,t; (c) rarr p;(d) rarr p,q,t`

On mixing entropy (disroder) always increase (P) `F_(A-A) & F_(B-B) =` Dipole - Dipole `lt F_(A)-B` [H-Bond]
`:.` Negative deviation from ideal solution
`DeltaH_(miax) lt 0 (r)`
Those solutions which exihibt negative deviation form maximum boiling axeotrope(s)
