Organic Chemistry

Question 0

Homologous series

Answer 0

Is a series of organic compounds with the same functional group (so similar reactions) but with each successive member differing by CH2

Question 1

Functional group

Answer 1

A group of atoms in an organic compound responsible for its chemical reaction.

Question 2

Empirical formula

Answer 2

The simplest whole number ratio of atoms of each element present in a compound.

Question 3

Molecular formula

Answer 3

The actual number of each element present in a molecule.

Question 4

General formula of Alkanes? Alkenes?

Answer 4

Alkanes: CnH2n+2
Alkenes: CnH2n+1

Question 5

Structural formula

Answer 5

The minimal detail that shows the arrangement of atoms in a molecule, Eg. CH3CH2OH

Question 6

Displayed formula

Answer 6

This shows how all the atoms are arranged and ALL the bonds between them.

Question 7

Skeletal formula

Answer 7

Shows the bonds of the carbon skeleton. Only shows any functional groups- does not show H’s bonded directly to C

Question 8

Structural isomers

Answer 8

Compounds with the same molecular for,USA but have different structural formula.

Question 9

Stereo isomers

Answer 9

Compounds with the same molecular and structural formula but a different arrangement of atoms.

Question 10

Functional group isomers

Answer 10

Compounds with different functional groups.
Eg. C3H6O
Propanone and Propanal

Question 11

Positional isomers

Answer 11

Compounds with the same functional group but in a different position.
Eg C3H8O
Propan-1-ol and Propan-2-ol

Question 12

E/Z isomerism

Answer 12

A compound with a C=C (restricted rotation) and 2 different grooms attaches to each carbon (cis/trans is a special case of E/Z isomerism).
Eg C4H8
Cisbut-2-ene and transbut-2-ene

Question 13

Hydrocarbons

Answer 13

Compounds that contain carbon and hydrogen only

Question 14

Satuated

Answer 14

Contains only single bonds (maximum number of hydrogens)
