Multiple Choice
Which of the following best describes constitutional isomers?
A
Compounds that are mirror images of each other
B
Compounds with different but similar physical properties
C
Compounds with the same but different connectivity of atoms
D
Compounds with the same connectivity of atoms but different spatial arrangement
Verified step by step guidance1
Begin by understanding the concept of isomers in organic chemistry. Isomers are compounds that have the same molecular formula but differ in some aspect of their structure or arrangement.
Constitutional isomers, also known as structural isomers, are a specific type of isomer. They have the same molecular formula, meaning they contain the same number and types of atoms.
The key characteristic of constitutional isomers is that they differ in the connectivity of atoms. This means the atoms are connected in different ways, leading to different structures.
Contrast constitutional isomers with stereoisomers, which have the same connectivity of atoms but differ in the spatial arrangement of atoms. This distinction is crucial in understanding the different types of isomers.
Review examples of constitutional isomers to solidify your understanding. For instance, consider C4H10, which can exist as butane or isobutane, demonstrating different connectivity despite having the same molecular formula.
