18. ) Number each carbon in the chain; so that, the side chains will be connected to the lowest possible numbers on the carbons

19. C Hexane

20. ) Name the side chains or substituted groups, & precede them with the # of the carbon they are connected to & a dash

21. C 2-methyl
C1 C2 C3 C4 C5 C6
C C C
2-methyl 4-ethyl

22. ) If identical groups appear more than once, use prefixes: di for 2, tri for 3, tetra for 4, penta for 5, etc Examples: dimethyl, tripropyl, etc

23. C 2,2-dimethyl
C1 C2 C3 C4 C5 C6
C C C
4-ethyl

24. ) Name the sidechains or groups in alphabetical order, but ignore the prefixes when doing so
Examples: ethyl comes before dimethyl, e < m

25. ) Separate numbers with commas, use hyphens between words & numbers, and write the alkanes as one word
Example: dimethylhexane
