Question 1

What is the definition of isomers?

Answer 1

compounds with the same chemical formula, but different structures.

Covers over:

• constitutional isomers.
• stereoisomers.

Under stereoisomers there are:
1) cis and trans isomers.

2) enantiomers (mirror images) and diastereomers (non mirror images)

3) configurational diastereomers and cis-trans diastereomers.

Question 2

what is constitutional isomers?

Answer 2

Compounds whose atoms are connected differently but have the same chemical formula.

1) different carbon skeleton

2) different functional groups.

3) different positions of functional groups.

Question 3

what is stereoisomers?

Answer 3

compounds whose atoms are connected in the same order, but with different spatial arrangement.

1) enantiomers and diastereomers.

2) cis and trans arrangements of cycloalkanes.
