Organic Chemistry

Question 1

What is a hydrocarbon?

Answer 1

Compound made only from carbon and hydrogen.
Bonds are single = saturated
Bonds are double/triple = unsaturated

Question 2

What are alkanes?

Answer 2

Family of hydrocarbons containing only one single bond

Question 3

Alkane formula?

Answer 3

Cn H2n+2

Question 4

Substitution reactions?

Answer 4

One or more of chlorine or fluorine (gas so F2) atoms switches place with a hydrogen, and forms alkane with three hydrogens and F plus HF

Question 5

What are alkenes?

Answer 5

Family of hydrocarbons with only one double bond

Question 6

Alkene formula?

Answer 6

Cn H2n

Question 7

Homologous series?

Answer 7

Each successive member differs from the one before it by CH2

Question 8

Addition reactions?

Answer 8

Hydrogen or halogen attacks double bond and breaks it. Alkenes join together to form long polymers

Question 9

What are alkynes?

Answer 9

Family of hydrocarbons containing one triple bond.

Question 10

Alkyne formula?

Answer 10

Cn H2n-2

Question 11

Cyclic hydrocarbons?

Answer 11

Benzene, C6H6 crude oil

Three single bonds and three double bonds. Hexagonal.

Question 12

What are isomers?

Answer 12

Organic molecule sharing the same molecular formulae but different structural formula

Question 13

What is organic chemistry?

Answer 13

The systematic study of the compounds of carbon. Compromise over 90% of all known chemicals.
