Question 10

Nonane

Answer 10

C₉H₂₀

Question 11

Alkyl

Answer 11

An Alkane minus a Hydrogen. In place of Hydrogen, the alkyl will bond to something else.

Question 12

How to name alkanes

Answer 12

1. name the longest alkane. This is the parent chain
2. name the substituent alkyl groups in alphabetical order
3. us multipliers to indicate number of identical substituents (di, tri, tetra, penta)
4. number the parent chain from the end. Start on side with substituents closest to the edge.
5. Number the substituents
