Draw 2-methylbutan-2-ol

How this exercise works

1. 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.
2. Press Check answer. Equivalent drawings are accepted, and a mistake such as a missing carbon or a misplaced group is explained.
3. 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.
