What are constitutional isomers?
A: Compounds with the same molecular formula but different connectivity of atoms.
What are stereoisomers?
A: Compounds with the same molecular formula and connectivity but differ in the spatial arrangement of atoms
Give an example of constitutional isomers from the slide.
A: 2-methylpentane and 3-methylpentane.
Provide an example of stereoisomers from the slide.
A: Cis-1,2-dimethylcyclopentane and trans-1,2-dimethylcyclopentane.
What distinguishes cis-1,2-dimethylcyclopentane from trans-1,2-dimethylcyclopentane?
A: The spatial arrangement of the methyl groups: cis has them on the same side, while trans has them on opposite sides.
How do the names of stereoisomers differ?
A: Stereoisomers have the same name except for a prefix like cis or trans.
What do constitutional isomers and stereoisomers have in common?
A: Both have the same molecular formula.
