Stereoisomers

Question 1

Cis

Answer 1

Compounds around double bond that are the same and on same side

Question 2

Trans

Answer 2

Compounds around Double bond with that are the same but on opposite sides

Question 3

Chiral molecules

Answer 3

Compound contains at least one chiral center

Question 4

Achiral

Answer 4

2 mirror images forms are superimpossible

Has a plane of symmetry

Question 5

Chiral center

Answer 5

Carbon with 4 different atoms or compounds attached to it (asymmetric center)

Question 6

Enantiomers

Answer 6

Differ at all chiral centers

Question 7

Cahn ingold prelog rules

Answer 7

1. Rank substituents at chirality Centers according to atomic number
2. Orient molecule so lowest ranked substituent points away from u

Question 8

R

Answer 8

Clockwise order of ranking

Question 9

S

Answer 9

Counterclockwise order of ranking

Question 10

Two groups have same atom when figuring out absolute configuration

Answer 10

Move out to another bond attached to it and compare atomic numbers of those numbers

Question 11

How many stereoisomers

Answer 11

2^n

n= chiral centers

Question 12

Diastereoisomers

Answer 12

Differ to at least 1 or more chiral centers but not all (must have at least 2 chiral centers)

Question 13

Meso

Answer 13

Have a plane of symmetry and could or couldn’t have chiral centers

Question 14

Racemic mixtures

Answer 14

Containing equal amounts of Enantiomers which is optically inactive

Question 15

Optically active

Answer 15

Not meso and not racemic
