| How are the terms, 'primary', 'secondary' and 'tertiary' different when applied to amines as opposed to haloalkanes? | In haloalkanes they refer to the number of substituent groups attached to the carbo that is bonded to the O-H group. In amines, they refer to the number of substituent groups on the nitrogen atom. |
| Why is phenylamine insoluble? | The benzene ring doesn't allow it to form hydrogen bonds. |
| amine+acid= | ionic salt |
| ethylamine +HCL= | ethylammonium chloride |
| arylamine+excess acid= | salt |
| salt+base= | amine+water |
| Why is phenylamine a weaker base than dimethylamine? | In phenylamine, the lone pair of electron overlaps with the ring of delocalised electrons in the benzene so they too become delocalised, hence they are less available to be donated to H+ ions. /In dimethylamine, there are two alkyl groups so the positive inductive effect is increased hence making the amine a better base. |
