Define a homologous series in organic chemistry.
A homologous series is a collection of inorganic compounds with varying functional groups.
A homologous series consists of compounds that differ by -OH groups only.
A homologous series is a single compound with multiple functional groups.
A homologous series is a group of organic compounds with the same functional group and a general formula, differing by -CH2- units.
What is the difference between structural isomers and stereoisomers?
Structural isomers differ in connectivity; stereoisomers differ in spatial arrangement.
Stereoisomers have different molecular formulas than structural isomers.
Structural isomers are always larger than stereoisomers.
Structural isomers are a type of stereoisomer.
