Organics

Question 1

CO + NO ->

Answer 1

CO2 + 1/2N2

Question 2

Substitution

Answer 2

Can be free radical, or nucleophilic

Question 3

Free radical substitution

Answer 3

Cl• regenerated

Question 4

Electrophile

Answer 4

Electron pair acceptor

Question 5

Remember that when counting carbon chains

Answer 5

Count the longest chain, and then identify methyl groups

Question 6

Incineration

Answer 6

• toxic products

* can use energy released

Question 7

Polymer melts over different temperature because it is

Answer 7

A mixture of chains of different lengths

Question 8

OH- base

Answer 8

Accepts H+

Question 9

Halogenoalkane + OH - ->

Answer 9

Alkene + halide + water

Question 10

Bulky methyl groups

Answer 10

Prevent access to C

Question 11

What is the nucleophile?

Answer 11

Is it H2O?

Question 12

Short bonds

Answer 12

require more energy to break

Question 13

Halogenoalkane + ammonia

Answer 13

Amine + halide + ammonium

Question 14

Propanol

Answer 14

1 or 2

Question 15

Alcohol oxidation

Answer 15

Produces water

Question 16

If there are more products than you were expecting

Answer 16

Is there E/Z isomerism?

Question 17

Alcohol solubility

Answer 17

• both involve breaking hydrogen bonds between alcohol molecules and between water molecules
• miscible if it forms as many hydrogen bonds as are broken
• immiscible is alkyl chains cause many more hydrogen bonds to be broken between water molecules that are formed between alcohol and water

Question 18

free radical

Answer 18

species with an unpaired electron

Question 19

Why does H2 not form in free radical substitution?

Answer 19

• C-H bond is too strong

- H* does not form (which would be needed to make H2)

Question 20

Why is yield of free radical substitution low, even if there is only one substitution

Answer 20

has it made an isomer? functional group occurs in different places?

Question 21

alkene + acidified potassium manganate eqn

Answer 21

alkane + [OH] + H2O -> diol (on each alkene carbon)

Question 22

uses for polymers

Answer 22

feedstock for cracking

Question 23

if there are more products than you’re expecting

Answer 23

have they made more stereoisomers?

Question 24

alkene halogen substitution

Answer 24

one bromine adds to each alkene carbon (don’t add both to one)

Question 25

alcohol substitution with bromine

Answer 25

• 50% conc. H2SO4

- KBr

Question 26

alcohol + PCl5 ->

Answer 26

halogenoalkane + POCl3 + HCl

Question 27

to show different enantiomers

Answer 27

swap longer carbon chains

Question 28

acyl chloride + amine ->

Answer 28

• keep acyl chloride R structure and carbonyl group, then attach amine where chlorine was
• attach amine R group instead of one H on the amine group
