Amines

Question	Answer
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.
