Draw cyclohexanol
Draw the skeletal structure of cyclohexanol, then check it. The checker compares the molecule you drew with the answer, so a correct structure is accepted however you draw it.
How this exercise works
- Open the exercise in the editor and draw the structure: drag from dot to dot to draw bonds, and tap a bond or an atom to change it.
- Press Check answer. Equivalent drawings are accepted, and a mistake such as a missing carbon or a misplaced group is explained.
- Stuck? Hints reveal the structure step by step, and the worked answer explains the name.

How to read a name like this
The suffix -ol means an OH group on a carbon of the chain. The number before -ol is that carbon, and the chain is numbered to give it the lowest possible locant, before double bonds and substituents; -diol and -triol mean two or three OH groups.
Hydroxy- is the prefix form of the same group, used when a group that ranks higher gives the suffix. An ether is named with an alkoxy prefix such as methoxy- or ethoxy-: an oxygen bonded to the parent on one side and to another carbon group, usually the smaller one, on the other.
In the drawing the oxygen is written out: with its H in an alcohol, between two carbons and without H in an ether.
Rules this name uses
- Cyclo- means that the carbons of the parent form a ring. C1 is the ring carbon with the suffix group if there is one; in a cycloalkene without a suffix, the double bond joins C1 and C2; otherwise C1 carries a substituent. The ring is then numbered in the direction that gives the lowest locants.
