Question

3. Part A −Br−I−OH− C 2 H 5 Rank from largest to smallest. To rank items as equivalent, overlap them. 3. Part B − CH 2 CH 2 OH−OH− CH 2 Cl−CH= CH 2 Rank from largest to smallest. To rank items as equivalent, overlap them.

Answer 1

3. Part A

Priorities increases as atomic number increases. So iodine has more priority than bromine and oxygen has less priority than bromine. As atomic number of carbon is less than oxygen, carbon has less pririty than oxygen. Therefore the ranking from largest priority to smallest priority is given as follows:

(highest priority) (lowest priority)

3. Part B

-CH=CH₂ has more priority than -CH₂CH₂OH.

This is because alkene is considered as -CH(C)-CH₂(C). This means -CH=CH₂ has more priority

(highest priority) (lowest priority
