What is the molecular formula of isomers? expanded structural formula? condensed structural formula? ^^,?
Answer:
I give you an example :
we heve to write all isomers of C5H12
1) CH3CH2CH2CH2CH3 n-pentane
2 ) CH3 CH CH2CH3 2-methyl-butane
**********CH3
3 )°°°°°°CH3
°°°°CH3CCH3 2,2- dimethyl propane
°°°°°°°°°°CH3
So you have to use an expanded structural formula
google it!

They have identical molecular formulas except they are different substances.
Example Pentane and 1-Methyl-Butane
Both have the molecular formula of 5 parts Carbon and 12 parts Hydrogen--except they're different substances.
This is a condensed formual for pentane: CH3CH2CH2CH2CH3
This is an expanded version of pentane:
..H.H.H.H...H.
H..C.C.C.C...C...H.
..H.H.H.H...H
