Answer» <P> Solution :It is DUE to the large size of `CD_(3)F`, but `D` is less `EN` than `H. (mu = q xx d)`. b. It is due to intramolecular `H-` bonding in `8-` hydroxy-quinoline. c. i. It is due to `H-` bonding in `CH_(3)OH`. ii. In the absence of `H-` bonding high MOLECULAR mass of `C_(2)H_(5))_(2)S` has higher point than `(C_(2) H_(5))_(2)O`. the aliphatic`(-NH_(2))` group is sufficiencty basic to accept`H^(o+)` from `(-COOH)` and exists as a dipolar ion (zwitterion), wheras in `PABA` (`p-` aminobenzoic acid,) an aromatic acid, `(-COOH)` is not strong enough to DONATE `H^(o+)` to a MUCH weaker base `(Ar-NH_(2))`. So the dipolar ion is not fomed. f. It is formed by propronation and susequent elimination of `H_(2)O`, followed by `H^(o-)` ion transfer to from a more stable carbonium ion.
