Question

Arrange the following groups in order of decreasing priority that would allow you to determine E/Z, or R/S. a)-OCH3 b)-CH(CH3)2 C)-COCH3 d)-H Provide a string of letters (e.g. abcd) as an answer with the highest priority listed first, lowest priority last Arrange the following groups in order of decreasing priority that would allow you to determine E/Z, or R/S. c)-Br Provide a string of letters (e.g. abcd) as an answer with the highest priority listed first, lowest priority last: a)-CH3 b)-H d)-COOH

Explanation / Answer

1)

1st atom is O in a , C in b and c , H in d

SO,

a > b or c > d

between b and c, at 2nd point there is O in c

So, C gets more priority than b

Answer:

acbd

2)

1st atom is C in a, H in b, br in C, C in d

so, order is:

c > a or d > b

between a and d, d gets more priority because of O

So the answer is

Answer:

cdab
