Organic - 3.1 Intro

Question 1

Define chain isomer

Answer 1

Isomers that occur due to the branching in the carbon chain.

Question 2

Define displayed formula

Answer 2

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

Question 3

Define empirical formula

Answer 3

The smallest number ratio of atoms of each element in a compound

Question 4

What is E-Z isomerism?

Answer 4

Type of stereoisomerism that occurs due to the restricted rotation around the carbon double bond. This results in two different groups on one end of the band and two different groups on the other end. If the highest priority for each carbon are found on the same side of the molecule, then it is the z-isomer. If the highest priority groups for each carbon are found an opposite sides of the molecule, then it is the e-isomer.

Question 5

What is a free radical

Answer 5

And uncharged molecule atom with an unpaired valence electron

Question 6

Define Functional group

Answer 6

The group of atoms responsible for the characteristic reactions of a particular compound

Question 7

Define functional group isomers

Answer 7

Molecules that contain different functional groups. This means they belong to different homologous series.

Question 8

Define homologous series

Answer 8

Series of compounds with the same functional group and similar chemical properties. For example, alkanes belong to the same series.

Question 9

Define position isomer

Answer 9

Isomers where the carbon backbone of the isomers are the same but the important groups are at different positions on the backbone

Question 10

Define skeletal formula

Answer 10

A diagram representation of an organic compound in which lines represent bonds between atoms and atoms are represented by the symbol. Hydrogens are assumed to be at the end of the line if no other atomic symbol is present.

Question 11

Define stereoisomerism

Answer 11

Occurs when two double bonded carbon atoms each have two different atoms or groups attached to them. Includes E-Z isomerism. This is a consequence of a restricted rotation around the C=C double bond.

Question 12

Define structural formula

Answer 12

A formula which shows the arrangement of atoms in the molecule of a compound but does not show all the bonds between them.

Question 13

Define structural isomerism

Answer 13

Structural isomers are compounds which have the same molecular formula but a different structural formula
