Naming Alkanes: find and name the longest...

carbon chain

Naming Alkanes: # the chain consecutively starting at the end closest to the...

substituent group (branch)

Naming Alkanes: Use #ed chain to label branches, in what order?

alphabetically (Example; 5, bromo, 3 ,iodopentane)

Naming Alkanes: use prefixes to...

indicate number of substituent (Example; 3,5, dibromopentane)

Naming Cycloalkanes: find cycloalkane (closed shape) and use that as...

root name

Naming Cycloalkanes: in a cycloalkane with only one branch the location is...

unnecessary (Ex; bromocyclobutane)

Naming Cycloalkanes: if two substituents are attached to the cycloalkane then they are listed in...

alphabetical order

Naming Cycloalkanes: when numbering the cycloalkane, start with the substituents first in the alphabet and the more clockwise or counter-clockwise so that the next possible substituent...

is the lowest number

Naming Cycloalkanes: list substituents in alphabetical order, using number system to name cycloalkanes

Ex. 1, 2 dichloro, 3, iodocyclopropane
