Chemistry 11 Naming Cyclos and Aromatics

Cycloalkanes are named using the alkane parent with the suffix cyclo. The general formula for the cycloalkanes is CnH2nIn naming branched cycloalkanes: • If there is only one substituent, no number is needed since that ring position attached would be #

1. • If there are two branches, the # 1 carbon would be listed first in the alphabetical order.• Number toward the second substituent in the direction which yields the lower number for the

carbon bearing that second substituent.

Cyclic hydrocarbons with multiple carbon – carbon double bonds form a special group of compounds called aromatic hydrocarbons. • The simplest member of this group is benzene (C6H6).

Substituent groups replace the hydrogen and are named as derivatives of benzene.The different structures of when there are two substituent groups are shown below. Number according to the rules of cycloalkanes.
