Chirality

Question 1

chiral

Answer 1

• molecule contains 4 unique groups
• NOT symmetrical
• contains no double bonds
• examples: hand or screw

Question 2

achiral

Answer 2

• molecule has two or more groups that are the same
• contains symmetry
• may contain a double bond
• examples: nail or pencil

Question 3

2^n

Answer 3

how to find the maximum number of stereoisomers, where n=number of chirality centers

Question 4

superimposable

Answer 4

when objects are identical and have multiple ways of orientation to stack them and they still look identical

Question 5

enantiomers

Answer 5

• non-superimposable
• they are mirror images
• molecule arrangement is the complete opposite of each other
• have identical physical properties (like melting/boiling/density)
• have different chemical properties (like toxicity/taste/smell)
• will rotate light in opposite directions

Question 6

diastereomers

Answer 6

• non-superimposable
• non-mirror images
• contain some parts of identical arrangement and contain some parts of different arrangement
