What if you want to describe a molecule, but you have nothing but a keyboard? (No fancy pictures or drawings). This is was actually a big dilemma in the chemistry world, which is why we now have condensed structure.
The condensed structure shows us the connectivity of the molecule. The use of parentheses is important:
This is similar to normal condensed structure, except there is a bondline ringed component. Always draw your condensed letters in terms of connectivity!
Remember, the exact direction of your zig-zag pattern doesn’t matter as long as everything is connected correctly. Single bonds can rotate freely, so let’s not spend lots of time worrying about the exact angles you drew.
