Draw an alkyl or conjugated chain with arbitrary length.
Draw a Chain
After selecting the Chain button you can draw the alkyl chain by dragging or clicking repeatedly on the starting atom.
The length of the chain is shown on the tip of the cursor. During drawing, the new chain can be rotated around its starting atom to the desired orientation by dragging.
You can create a conjugated polyene chain by holding down the Ctrl button when chain-drawing.
