Q

What happens if Hydrogen is added to a alkene?

A

The double bond is easily broken under high temperature because only the first bond formed between atoms is a sigma bond which is the easiest to break.

Q

Adding HX to alkene X = (Cl, F, Br, I)

A

The addition of hydrogen halides is one of the easiest electrophilic addition reactions because it uses the simplest electrophile: the proton. Hydrogen halides provide both a electrophile (proton) and a nucleophile (halide).

These halides are (HBr, HCl, HI, HF), these can participate in this reaction and add on in the same manner. Although different halides do have different rates of reaction, due to the H-X bond getting weaker as X gets larger (poor overlap of orbitals)s.

Q

Name and describe the making of long polymer molecules.

A

Polymerization

This is done by breaking the double bond and using it to connect the molecules.

In this example ethene is used to make the plastics polyethene.

Aldehydes are carbon chains with a oxygen attached at the end of the chain.

With a double bond.

e.g.

25
Q

A

In Ketones the oxygen is attached to the middle of the chain.

e.g.

26
Q

-al

Keytone suffix:

-one

27
Q

A

Ethanoic acid:

28
Q

What is the suffix for a carbonoic acid?

A

Carbonoic acid suffix:

-oic acid

29
Q

What is the diffrence between a carboxylic acid and an ester?

A

An ester is made by replacing the hydrogen of a carbonoic acid by an alkyl or other organic group.

30
Q

Draw the structure of a simple ether.

e.g.

(Methoxymethane)

A

It is used to connect to organic compounds like so:

31
Q

Draw the structure of a simple amine.

e.g.

(N-ethane-1-amine)

A

Amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair.

e.g.

32
Q

What is the suffix for amines?

A

Amine suffix:

-amine

33
Q

What is the diffrence between an amine and amide?

A

The main difference between amine and amide is the presence of a carbonyl group in their structure; amines have no carbonyl groups attached to the nitrogen atom whereas amides have a carbonylgroup attached to a nitrogen atom.

34
Q

What is a nitrile?

A

A nitrile is an organic chemical in which the carbon and nitrogen atoms have a triple bond i.e. C≡N-.

What is a tertiary alcohol?

A

Tertiary alcohol:

A tertiary alcohol is a compound in which a hydroxy group, ‒OH, is attached to a saturated carbon atom which has three other carbon atoms attached to it. e.g.

Name all Isomers to do with Organic chemistry.

A
48
Q

What are optical Isomers?

A

Optical Isomers are those which contain a chiral carbon, that is, it contains four different groups. Optical Isomers often have closely similar chemical properties. These are super impossible.

49
Q

How is a polarimeter used?

A

The polarimeter is used to measure the angle of rotation caused by passing polarized light through an optically active substance.

50
Q

What are enantiomers?

A
