shows arrangement of atoms carbon by carbon.
6
Q
homologous series
A
group of compounds with the same general formula, same functional group, similar chemical properties and a gradual trend on physical properties
7
Q
functional group
A
group of atoms that determine how compound typically reacts
8
Q
isomers
A
have same molecular formula but atoms are arranged differently, so their structural formula is different.
