Isomers differ in the arrangement or bonding of atoms.
To elaborate:
- Isomers are compounds that have the same molecular formula but differ in their structure or arrangement of atoms.
- There are several types of isomers, including:
- Structural isomers, which have different connectivity of atoms (e.g., different chain lengths or functional groups).
- Stereoisomers, which have the same connectivity but differ in the spatial arrangement of atoms (e.g., cis-trans isomers or enantiomers).
The first two statements are not accurate:
- Isomers do not necessarily differ in charge; they may have the same charge.
- While isomers have the same molecular formula, they differ in structure.
So, the correct distinction is based on the arrangement or bonding of atoms.
