Question

I need help, please, with the following question:

Match the following groups sccording to their priority (lowest group = 4 & highest group =1)

Matching Pairs: Priority rank options:

-CH2CH3 3,4,2,1

-CH2NH2 3,4,2,1

-CH2Br 3,4,2,1

-CH2OH 3,4,2,1

Answer 1

I think that the order should be:

-CH2CH3 = Priority #4

-CH2NH2 = 3rd priority

-CH2Br = 1st priority

-CH2OH = 2nd priority

Does this look right???
