What are four isomers of dichloropropane?

Answer 1

Emilia Alvarez

They are 1,1-, 1,2-, 1,3-, and 2,2-dichloropropane.

You work out all the different combinations of positions.

1,1-, 1,2-, and 1,3-, and 2,2- are all different.

2,3- is not different, because it is equivalent to 1,2-.

This gives us the four dichloropropanes.

From top to bottom, the structures above are

1,1-dichloropropane
1,2-dichloropropane
1,3-dichloropropane
2,2-dichloropropane

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
