Ready to TEST your understanding of drawing skeletal structures from condensed formula and back again?
This quiz is designed to follow my Drawing Skeletal Structures Tutorial Video.
Memorizing concepts it NOT enough. This quiz will help you determine if you've MASTERED this topic. Be ready to ace this topic on your next Organic Chemistry exam!
The skeletal video uses simple examples to demonstrate concepts; these questions will test you at a slightly higher level.
Already past this topic but need a review?
So give it a shot! See how you do, then download the PDF solutions at the end of the quiz.
Part 1: Convert the following condensed and Lewis Structures into Line structures
Part 2: Count the number of Carbon and Hydrogen atoms in each of the following molecules
Part 3: Convert the following Line structures/skeletal structures to condensed formula AND Lewis Structure

I’m practicing naming these also, do you have the names to check if I named them correctly?
Hi im srinidhi from india
Love they way you teach ,you are definitely a lifesaver for many across the world keep going
Amazing help for my upcoming O. Chem test! Thanks so much. 🙂

This was very helpful prep for test 1. Thanks !
part 1c 1d and f are very confusing and if you plz explain
could you please explain part 2b? why is there only 1 bond connected to the 2nd carbon from the left? should it be two? thanks

As an instructor (Dr. Gary Hiel) am teaching a 1-week Short Course as prep for Organic at Suffolk Co Community College (NY) We use a wonderful, economical paperback text. One of its few flaws is a lack of explicit exercises in interconverting Lewis and Line- bond structures. pressed for time to make up examples , your content fits the bill perfectly, . Thanks You!
PS: it helps that your hand-dawn structures are carefully done and virtually equivalent to print. I also make abundant use of color, as you do.
It was a bit challenging to turn the line skeletons back to a condensed formula

Your questions were very good and informative

I am teaching Organic Chem to high school students and we love your videos! Thanks for this great resource.
I really enjoyed the practice. However, part 3 E, I believe on the 3rd C from the left, you’re missing a H on the C.
