E/Z isomers

Question 1

What are stereoisomers?

Answer 1

Same structural formula but a different arrangement for atoms in 3D space

Question 2

What are the conditions for a molecule to be an E/Z isomers?

Answer 2

It must contain a C=C bond and it must average two different groups of atoms attached to each carbon in the C=C

Question 3

Why do alkenes for E/Z isomers?

Answer 3

The C=C bond is unable to rotate

Question 4

How do you decide the priority group?

Answer 4

The atom directly attached with the highest atomic number. If they are the same, list the atomic numbers one bond further out and the first group with a highest number, is the priority group.

Question 5

How do you decide the priority group is the first two atoms are the same?

Answer 5

List the atomic numbers one bond further out and the first group with a highest number, is the priority group

Question 6

What is a Z isomer?

Answer 6

The priority groups are on the same side

Question 7

What is an E isomer?

Answer 7

Priority groups are on opposite sides of the

Question 8

What is cis/trans isomerism?

Answer 8

When one of the groups attached to each carbon of the double bond is the same

Question 9

What is a cis isomer?

Answer 9

The matching groups are both on the same side

Question 10

What is a tans isomer?

Answer 10

When the matching groups are on opposite sides of
