Unit 1

Question 1

Alkane/ ene/ yne polarity

Answer 1

Non polar

Question 2

Alkane/ ene/ yne main intermolecular force

Answer 2

London dispersion

Question 3

Alkane/ ene/ yne Mp/Bp

Answer 3

Low but get higher as the chain gets longer

Question 4

Organic Halides polarity

Answer 4

More polar than hydrocarbons which means higher mp/ bp and more soluble. The more halogens there are, the more polar it gets

Question 5

Alcohols polarity

Answer 5

Polar, they form hydrogen bonds so higher mp/ bp

Short chain alcohols are good polar solvents

Long chain alcohols are good polar and non polar solvents

Question 6

Ethers polarity

Answer 6

Can not form hydrogen bonds but the oxygen makes it more polar than alkanes

Good as a polar and non polar solvent because it is very chemically stable

Question 7

Aldehydes and ketones polarity

Answer 7

Both polar and non polar, good solvents. Less soluble in water that alcohol because there is no hydrogen bonding

Question 8

Ethers mp/bp

Answer 8

Mp/ bp is higher than alkanes but lower that alcohols and water

Question 9

Aldehydes and ketones mp/ bp

Answer 9

Lower than alcohols

Question 10

Carboxylic acids polarity

Answer 10

Polar and form hydrogen bonds
Similar solubilities to alcohols
Behave like other acids

Question 11

Carboxylic acids mp/bp

Answer 11

higher mp/bp than alcohols

Question 12

Which side of esters goes first

Answer 12

Carboxylic acid

Question 13

Ester polarity

Answer 13

Less polar than the parent acid and alcohol which leads to lower mp/ bp

Question 14

Ester at room temp

Answer 14

Gasses. Lower molecular mass

Question 15

Amines mp/bp

Answer 15

Higher than alkanes

Question 16

Amines solubility

Answer 16

Smaller molecules are more soluble

Question 17

Amines smell

Answer 17

Fishy

Question 18

Amines Types of bonds

Answer 18

Hydrogen bonds

Question 19

Amines Bond polarity

Answer 19

Polar

Question 20

Amides properties

Answer 20

Weak bases, H+ receivers

Question 21

Amides solubility

Answer 21

Not soluble in water

Question 22

Amides Mp/ bp

Answer 22

If alkyl group is on the end they have lower mp/bp that if NH2 group is on the end

Question 23

Addition polymers

Answer 23

linkage by unsaturated carbon bonds

Question 24

Polyesters

Answer 24

Made from a dicarboxylic acid and a diol

Question 25

Polyamides

Answer 25

Made from an anime group and a carboxylic acid

Question 26

Alkanes substitution

Answer 26

Br2 turns into HBr

Question 27

Halogenation

Answer 27

Br2 breaks a double bond

Question 28

Hydrogenation

Answer 28

H2 breaks a bond (needs to be balanced)

Question 29

Hydrohalogenation

Answer 29

HBR breaks double bonds

Question 30

Hydration

Answer 30

H2O is used to form am alcohol

Question 31

Elimination (organic halides)

Answer 31

Strong acid or base is used to remove a halogen

Question 32

Dehydration (alcohols)

Answer 32

Alcohol turns into water and an alkene

Question 33

Answer 34

Aldehydes and keynote are formed

Question 35

Esterification

Answer 35

An ester is formed

Question 36

Hydrolysis/ saponificantion

Answer 36

A carboxylic acid and alcohol are formed from an ester

Question 37

Synthesis (amides)

Answer 37

Adding NH3 to a carboxylic acid

Question 38
