Structural isomer

Chemicals that have the same formula but the atoms are arranged in different organization

1

Single bonds have what kind of rotation

Free rotation

2

Double bonds have what kind of rotation

No rotation because the double bonds lock it into place

3

Cis means

Same side
H H
\ /
C==C
/ \
HOOC COOH

4

Trans means

Different side
HOOC H
\ /
C==C
/ \
HOOC H

5

What is the only difference between cis and trans

The orientation around the double bond

6

Unsaturated fats use what kind of bonds

Cis- double bonds

7

What is a tetrahedral

Carbons with four single bonds have a tetrahedral geometry

8

What is a stereoisomer

They are identical to each other except for they are not superimposable mirrors of each other

Chiral molecules**

9

Enantiomers

They are mirror images of each other.

Ex: All four groups on the molecule are different from each other we can't superimposed them on top of each other but we can reflect them in the mirror.

11

R configuration

Turns left (clockwise)

12

S configuration

Turns right (counterclockwise )

13

How do you figure out if it is a R or S shape

You add up the atomic weight of the first Adam if it is a tie then you add the weight of the next atomm to see which one is heavier

14

Glucose and fructose are what type of isomers

Structural

15

The type of double bonds found in most unsaturated fatty acid's are

Cis

16

A structure has a pH 6 another solution has a pH 5 the pH 5 solution is how many times more acidic than the pH 6 solution

10x

17

Solution has a pH 6 another solution has a pH 4 for the pH 4 solution how many times more acidic than the pH 6 solution

100x

18

A solution has a pH 6 another solution has a pH 10 the pH 10 solutions how many times more basic than the pH 6 solution

10,000

19

Drug with the carboxylate group will have what charge on that group if the pH of the solution is significantly less and it's pKa

0

20

A drug with the carboxylate group will have what charge on that group if the pH of the solution is significantly more then it's pKa

-1

21

A drug with the carboxylate group will have what charge on that group if the pH of the solution is the same as it's pKa

Half of the molecules will be -1 and half will be neutral
