Answer 2

Unsaturated

Question 3

Compounds that contain a benzene ring

Answer 3

Aromatic

Question 4

Examples of tetrahedral compounds

Answer 4

Alkanes, chloroalkanes and alcohols

Question 5

General formula for alkanes

Answer 5

CnH2n+2

Question 6

Uses for alkanes

Answer 6

Suitable fuels such as LPG made from propane and butane

Question 7

A chloroalkanes is described as

Answer 7

An alkane where one or more of the hydrogen atoms are replaced by a chlorine atom

Question 8

Di- and tri- prefix in chloroalkanes is needed when

Answer 8

More than one chlorine is present in the molecule

Question 9

What is the solubility and boiling point of chloroalkanes

Answer 9

Insoluble in water but soluble in cyclohexane, higher b.p. than corresponding alkane but only slightly

Question 10

Uses for chloroalkanes

Answer 10

Useful solvents used in dry cleaning

Question 11

General formula and name of group attached for alcohols

Answer 11

CnH2n+1OH, hydroxyl group

Question 12

Define a primary alcohol

Answer 12

Carbon attached to the OH group is bonded to only one other carbon

Question 13

Define secondary alcohol

Answer 13

When the carbon bonded to the OH group is bonded to two other carbons

Question 14

Physical properties of alcohols

Answer 14

Far higher b.p. than corresponding alkane as the OH group forms H-bonds with each other, soluble in water

Question 15

Uses of alcohols

Answer 15

Fermentation and distillation, also used as a solvent for glues and paints

Question 16

Planar carbons are said to have

Answer 16

Double bonds and are unsaturated

Question 17

Alkenes general formula

Answer 17

CnH2n

Question 18

What are the uses for alkenes

Answer 18

Used in the polymerization industry to create long chain hydrocarbons

Question 19

Aldehydes general formula and functional group

Answer 19

CnH2n+1CHO, CHO

Question 20

To name an aldehyde

Answer 20

Replace the -e with -al

Question 21

Physical properties and b.p.

Answer 21

Form dipole dipole forces and have a higher b.p. than corresponding alkane but lower than alcohol as it does not form H-Bonds

Question 22

Occurrence of aldehydes

Answer 22

Glucose and benzaldehyde (almonds)
