3. pick a suffix based on alkene/alkane
4. for branched carbon chains- add yl to prefix (1 carbon chain = meth +yl)
5. for duplicated chains, add di, tri, tetra, (two 2-C chains)= diethyl
6. alphabetize branches on the e and m, ignore di
7. commas b/w numbers; dashes between numbers and letters

cis/trans isomers
cis - same side

Name that molecule!
1. longest chain is 3 carbon
2. only single bonds
3. 1-C branch
4. branch is coming off the second carbon
1. longest chain is 3 carbon = prop-
2. only single bonds = -ane
3. 1-C branch = -methyl
4. branch is coming off the second carbon = 2-methyl
2-methylpropane
