Introduction To Organic Chemistry

Question 1

Empirical Formula

Answer 1

The smallest whole number ratio of elements in a compound

Question 2

Molecular Formula

Answer 2

Chemical formula of a molecular compound that shows the kinds and numbers of atoms present in the compound

Question 3

General Formula

Answer 3

A type of empirical formula that represents the composition of any member of an entire class of compounds e.g. alkanes = CnH2n+2

Question 4

Structural Formula

Answer 4

A ​formula which shows the arrangement of atoms in the molecule of a compound but does not show all the bonds between them. E.g. CH​3​CH​2​COCH​3​

Question 5

Displayed Formula

Answer 5

A type of structural isomer that shows all the bonds between every atom in the compound

Question 6

Skeletal Formula

Answer 6

A representation of organic compound in which the carbon chain is shown by lines with no carbons or hydrogens drawn

Question 7

Structural Isomers

Answer 7

Molecules that have the same molecular formula, but have a different arrangement of atoms

Question 8

Chain Isomer

Answer 8

When compounds have the same molecular formula, but their longest hydrocarbon chain is not the same · This is caused by branching

Question 9

Position Isomer

Answer 9

Functional group is attached to the main chain at a different place

Question 10

Functional Group Isomer

Answer 10

When substances have the same molecular formula but different functional groups

Question 11

Stereoisomer

Answer 11

When molecules have the same structural and molecular formula, but have a different arrangement of atoms in space

Including EZ and Optical
