how many carbons are in the following molecule?
a) 10
b) 6
c) 8
d) 9

Explanation:

Step1: Count carbon atoms

In a skeletal structure of an alkane, each line - junction and end - point represents a carbon atom.
Starting from the left - most end, count each carbon atom.
The left - most end is one carbon. Then, moving along the branches and the main chain:

• The first branch point: second carbon.
• The next junction (where the main chain and another branch meet): third carbon.
• The end of the lower - left branch: fourth carbon.
• Continuing along the main chain: fifth, sixth, seventh, eighth, ninth carbon.

Answer:

d) 9
