Q

What can carbon form ?

A

Can form 4 bonds with other carbon atoms or elements. Can form chains and rings due to strong covalent bonds with other atoms. Bonds can be single, double or triple.

Q

What is a functional groups ?

A

Functional group is responsible for characteristic reaction of a compound.

17
Q

What is a homologous series ?

A

A series of organic compounds having the same functional groups with each successive member member differing by CH2.

18
Q

What are isomers ?

A

Different compounds with the same molecular formula.

19
Q

What is structural isomerism ?

A

Compounds with the same molecular formula but different structural formula.

20
Q

What are the 2 types of bond fission ?

A

Homolytic fission and heterolytic fission.

21
Q

What is homolytic fission ?

A

When a covalent bond is broken by homolytic fission, each bonded atom takes one of the shared pair of electrons from the bond.
-Each atom has a single unpaired electron.
-An atom with an unpaired electron is called a radical.

22
Q

What is heterolytic fission ?

A

When a covalent bond is broken by heterolytic fission, one of the bonded atoms take both electrons from the bond.
-The atoms that takes both electrons becomes a negative ion.
-The atom that does not take electron become a positive ion.

23
Q

What is an organic reaction mechanism ?

A

Reaction mechanism is how the reaction takes place. They are shown through curly arrows to show movement of electrons when bonds are being broken or made. The number of arrow heads show how many electrons are moved.

24
Q

What is an addition reaction ?

A

In an addition reaction, two reactants join together to form one product.

25
Q

What is a substitution reaction ?

A

In a substitution reaction, an atom or group of atoms is replaced by a different atom to group of atoms.

26
Q

What is an elimination reaction ?

A

An elimination reaction involves the removal of a small molecule from a larger one. One reactant molecule forms two products.

27
