Hydrocarbons

Question 1

Alkane boiling points

Answer 1

As number of carbon and hydrogen atoms increase so does the boiling point

Question 2

Small alkane properties

Answer 2

Runny liquids, low boiling points, easy to burn, burn cleanly

Question 3

Large alkanes properties

Answer 3

Thick sticky liquids
High boiling point
Harder to burn
Burn with a smoky flame

Question 4

Halogenoalkanes general formula

Answer 4

CnH2n+1X

Question 5

Alcohol general formula

Answer 5

CnH2n+1OH

Question 6

Carboxylic acid general formula

Answer 6

CnH2n+1COOH

Question 7

Is C=C saturated or unsaturated and why

Answer 7

Unsaturated as not max number of H atoms attached

Question 8

Chain isomerism

Answer 8

Refers to molecules with a different main carbon chain despite the same number of elements

Question 9

Position isomerism

Answer 9

Refers to molecules with the same functional group attached to the main chain in different positions despite the same number of elements

Question 10

Cis stereoisomer

Answer 10

Same sides of the C=C

Question 11

Trans stereoisomers

Answer 11

Same element each side / diagonal from each other over the C=C

Question 12

When is E and Z notation used

Answer 12

When there are 4 different groups present

Question 13

E - isomers

Answer 13

Compounds with the highest and lowest priority or atomic number on the opposite side

Question 14

Z - isomers

Answer 14

Compounds with the highest priority on the same side
