Quiz 3 prep #4

Postby Michael Lonsway 3O » Sun Mar 05, 2017 2:42 pm

In the question below where do we start to number the carbon atoms? I'm not sure how to label the substituents in the cycloalkane since I don't know where we would start counting the carbon atoms.

In the case of cycloalkanes, the substituent with the highest priority will have the first number, and then work to find the lowest constituent numbering, see link for priorities:

In this case, the longer alkane chain will have higher priority and thus be named first.

How do we tell which substituent has the highest priority? What would it be in this example and how would you tell?
