Verified step by step guidance1
Understand the definition of constitutional isomers: Constitutional isomers are compounds that have the same molecular formula but differ in the connectivity of their atoms.
Analyze the given options: Identify which option correctly describes the definition of constitutional isomers.
Option 1 states that constitutional isomers have the same molecular formula but differ in the connectivity of atoms. This matches the definition.
Option 2 mentions a difference in spatial arrangement, which is characteristic of stereoisomers, not constitutional isomers.
Option 3 and 4 either describe identical connectivity or different molecular formulas, which do not fit the definition of constitutional isomers.
