Chapter 5-Tetrahedral Centers

Question 1

Enantiomer

Answer 1

A molecule that is not identical- Mirror immage

Question 2

A molecule with a plane of symmetry is chiral or achiral

Answer 2

Achiral

Question 3

A chiral molecule

Answer 3

A carbon with four different groups bonded to it

Question 4

Optically active

Answer 4

The plane of polarization is rotated

Question 5

Levorotatory

Answer 5

Optically active molecules rotate polarized light to the left (CC)(-)

Question 6

Dextrorotatory

Answer 6

Optically active molecules rotate polarized light to the right (C)(+)

Question 7

(-)-morphine

Answer 7

Levorotatory

Question 8

(+)-sucrose

Answer 8

Dextrorotatory

Question 9

Specific rotation formula

Answer 9

[α]D = observed rotation(degrees) / path length(l) X concentration(c) = α/lxc

Question 10

An atom with a higher atomic number has or does not have priority of an atom with lower atomic number?

Answer 10

Has

Question 11

Can you have chirality on nitrogen?

Answer 11

No

Question 12

Meso-compounds

Answer 12

Compounds that have chiral centres but have a plane of symmetry so they are achiral

Question 13

Diastereomers

Answer 13

Sterioisomers that are not mirror images

Question 14

Racemic mixture

Answer 14

50:50 mix of two chiral tartaric acid enantiomers.
The (+) rotation of one cancels the (-) rotation of the other

Question 15

R

Answer 15

Rectus - clockwise

Question 16

S

Answer 16

Sinister - counterclockwise
