Which of the following pairs would have higher boiling points ? |
|
Answer» Solution :(a) (II) because carbonyl GROUP is more polar than DOUBLE bond. (b) (I) acid forms dimar due to `H-`bonding. ( C) (II) cis-compound has high dipole moment `(mu)`, so more polar than trans-compound `(mu = 0)` (d) (I) it forms `H-`bonding1 through `H` atom in `(-NH)` group. ( e) (II) it forms `H-`bonding (f) (II) alcohols form `H`-bonding. (G) (II) two `(OH)` groups can form more `H-`bonding with each other. (h) (I) alcohold form `H-`bonding (i) (II) because of high MOLECULAR mass and large size, have larger van der Waals forces of attraction. |
