Carbon numbers: `1`, `2`, `3`, `4`, `5`, `6`, `7`, `8` 1: meth 2: eth 3: prop 4: but 5: hept 6: hex 7: sept 8: oct All single: `single`, double (make sure to prefix with carbon number/di if two): `double`, triple: `triple` single: an double: en triple: yn Suffixes: -H: `-h`, -oh: `-oh`, -nh2: `-nh2`, -x (halogen): `-x (for Cl)`, -COOH: `-COOH`, -C=O-OR: `-COOR` (`name`), -C=O-O: `-C=O-O` (`name2`), =O in the middle: `=O` (`name3`) -h: -e -oh: -ol -nh2: amino- -x (for Cl): chloro- -COOH: -oic acid -COOR: -oate name: ester -C=O-O: -al name2: aldehyde =O: one name3: ketone Things with -X are called halogenoalkane Thing with double bond O in the middle is ketone This is `type` molecule called `name` type: ester name: ethyl ethanoate This is what butan-2-one This is what 2,2,4-trimethylhexane
