What are the FOUR structural isomers of C2H5N?

Answer 1

The structure formulas of the four isomers of C3H9N are:

Propamine : CH3-CH2-CH2-NH2 : or : CH3-[CH2]2-NH2

Prop-2-amine : CH3-CH-NH2-CH3

EthyMethylamine : CH3-NH-CH2-CH3

TriMethylamine : N(CH3)3

Answer 2

I'm not sure if there is a particularly elegant way to do it. I use a systematic development method

to start, there are the primary amines which can be constructed.

butanamine CH3CH2CH2CH2NH2

2-butanamine CH3CHNH2CH2CH3

2 methyl propanamine CH3 CH(CH3)CH2 NH2

…

1,1 dimethyl ethanamine

CH3 C(CH3)2 NH2

Then the secondary amines

N-methyl propanamine

CH3CH2CH2NHCH3

N-ethyl ethanamine

CH3CH3NHCH2CH3

Finally the tertiary amine

N,N-dimethyl ethanamine

(CH3)2NCH2CH3

I count 7 constitutional isomers

Answer 3

2-butanamine

1-butanamine

1,1-dimethylethanamine

diethylamine

2-methylpropanamine

N,1-dimethylethanamine

N-methylpropanamine

N,N-dimethylethanamine

Answer 4

H2C=CH-NH2,

CH3-CH=NH,

CH2=N-CH3,

and

NH
