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
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
2-butanamine
1-butanamine
1,1-dimethylethanamine
diethylamine
2-methylpropanamine
N,1-dimethylethanamine
N-methylpropanamine
N,N-dimethylethanamine
H2C=CH-NH2,
CH3-CH=NH,
CH2=N-CH3,
and
NH

The three main types of isomers are structural isomers, geometric isomers, and enantiomers.
These are not optical isomers they are functional group isomers a subcategory of structural isomers.

Xylene has structural isomers.
There are Five structural isomers of C3H6Cl Br

Just try to draw the structures with different arrangements of carbon atoms having four valencies each, there are 5 isomers for this formula.

Pentane
Xylene has structural isomers.
There are Five structural isomers of C3H6Cl Br
pentane
None, as it has 5 structural isomers in which none of are optically active.
Molecules with the same molcular formulae but differing structural formulae are called isomers.
