Chemistry Unit: Part 2 (Organic Chemistry)

Question 1

What is organic chemistry?

Answer 1

It is the study of organic compounds containing carbon.

Question 2

What are hydrocarbons?

Answer 2

These are only hydrogen and carbon. It is also important to note that carbon always has 4 bonds. There are three different types of hydrocarbons:

• Alkanes: These all have single bonds “ane”
• Alkenes: This has at least one double bond “ene”
• Alyknes: This has at least one triple bond “yne”

Question 3

What does the prefix and suffix mean?

Answer 3

It is important to note that the prefix, can tell us how many carbon atoms there are in a molecule. Furthermore, that the suffix allows us to know what “family” (single/double/triple bond) it is in.

Question 4

Naming branched alkanes. What are the steps?

Answer 4

• The first thing you do is to circle the parent chain and label it as such (numbered).
• Then name it after how many carbons there are (name the branches as well).
• Afterwards number the parent chain.
• The way you write it shows the location of where it branched off from, and then how many carbons are in that branch.
