# How many carbons in this skeletal structure? [closed]

How many carbons are in this skeletal structure? I was told to draw a circle at the start of the structure and at each point the line turns off to get the total number of carbons but doing so would result in 6 carbons which I know is wrong but why is it wrong? And where on the structure are the carbons located?

Thanks for clearing this up for me!

• OK, you've described a procedure and immediately told us that it is wrong. How do you know it is wrong? Nov 29 '17 at 17:59
• Because 6 carbons just looks too many for the size of the structure in my opinion. Nov 29 '17 at 18:04
• What a weird way of counting the carbons. Just convert all the points where the lines join into a "C", then you should see how many you have. Nov 29 '17 at 18:06
• So as such this structure should have 3 carbons? Nov 29 '17 at 18:09
• Sorry, I wasn't clear - this is in addition to the ones that are already shown as "C". What is going on here is that 'terminal' carbons (at the end of a chain) can optionally be shown as element symbols (CH3) - you could equally convert these ones to points, and get just a line drawing.
