Compare the boiling points of 1^(@),2^(@) and 3^(@) amines. |
|
Answer» Solution :(i) The boiling point of various amines FOLOWS the order. `CH_(3)UNDERSET(1^(@))(-)overset(..)(N)H_(2)underset(gt)(gt)underset(2^(@))((CH_(3))_2)overset(..)(N)Hunderset(gt)(gt)underset(3^(@))((CH_(3))_(3)overset(..)(N)` (ii) Due to the polar nature of primary and secondary amines, can form intermolecular hydrogen bonds using their lone pair of electron on nitrogen atom. However, tertiary amins do not form intermolecular hydrogen bond and they have lower boiling point than `1^(@)` and `2^(@)` amines. |
