Basic Concepts of Organic Chemistry - Isomerism

Question 1

What is an isomer?

Answer 1

Isomers are molecules with the same molecular formular but different structural formula.

Question 2

What are the 3 classes of structural isomerism?

Answer 2

Chain isomerism, positional isomerism, functional group isomerism.

Question 3

What are positional isomers?

Answer 3

Isomers have the same carbon skeleton but differ in the position of functional groups.

Question 4

What are chain isomers?

Answer 4

Isomers have different arrangements of the carbon skeleton, including straight chains & branched chains.

Question 5

What are functional group isomers?

Answer 5

Isomers have the same atoms arranged into different functional groups.
