2 steps to alkylation of ammonia and amines .....Answer.....1.

ammonia as nucleophile displaces halide ion via Sn2 reaction


2.sodium hydroxide (base) added to deprotonate the

alkylammonium cation to produce the "free base" of the amine


what is the disadvantage of alkylation of amines?

.....Answer.....Polyalkylation: yield a mix of amine products

because no reaction stops cleanly after a single alkylation

,age 2 of 46




how to combat possible polyalkylation? .....Answer.....use large

concentration of ammonia or amines as the excess helps the

halides not react with the new amines created


amine aqueous solubility does what? .....Answer.....solubility

decreases as molecular weight increases


alkylation of ammonia and amines .....Answer.....alkyl halide

added to an ammonia to create an amine


what does a primary amine alkylate to? .....Answer.....secondary

amine (R2NH)


What does a secondary amine alkylate to? .....Answer.....tertiary

amine (R3N)


what does a tertiary amine alkylate to? .....Answer.....quaternary

ammonium salt

,age 3 of 46




what is advantage of alkylation of amines ? .....Answer.....can

produce all degrees of amines


derivative of ammonia where one or more hydrogen replaced

by carbon-based groups .....Answer.....amine


R-NH2 .....Answer.....primary amine


R2NH .....Answer.....secondary amine


R3N .....Answer.....tertiary amine


NH3 .....Answer.....Ammonia


a configuration in which nitrogen has four bonds with other

atoms and, as such, the molecule has an electron deficit

.....Answer.....quarternary amine

, age 4 of 46




naming simple amines .....Answer.....name by alkyl group +amine

at the end


.....Answer.....Ethylamine


.....Answer.....diethylamine


.....Answer.....triethylamine


.....Answer.....cyclohexylamine


naming amines with additional functional groups present

.....Answer.....name parent chain and then name amine as amino

substituent


.....Answer.....3-aminobutanoic acid


.....Answer.....2,4-diaminobenzoic acid


.....Answer.....N-ethyl-N-methylpropylamine
