Draw 1-chloro-3-methylbutane

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

Fluoro-, chloro-, bromo- and iodo- are substituent prefixes in front of the name of the parent alkane. Di-, tri- and tetra- say how many atoms of the same halogen there are, and each of them has its own locant.

Halogens and alkyl groups are numbered together, as equals: the chain is numbered to give all of them the lowest locants, and a tie goes to the prefix that comes first in alphabetical order.

In the drawing every halogen is a single atom at the end of a bond, written with its symbol: F, Cl, Br or I.

Rules this name uses

• Different prefixes are written in alphabetical order, whatever their locants. When both directions of numbering give the same set of locants, the prefix that comes first in the alphabet gets the lower number.
