Assign priorities in the following set of substituents according to Cahn-Ingold-Prelog rules. -NH2 -CH2OH -OH -Br A B C D (Provide your ranking through a string like abcd, starting with the one with the highest priority. Your answer does not need to be capitalized.)

Explanation:

Now to correctly assign priorities in the following set of substituents we need to consider the molecular weight of the atom that is been directly attached to  the carbon bond

Now an atom with a higher molecular weight will imply that the substituent will have the the highest priority

So  S (32.065 u)with a the highest molecular weight implies that -SH has the highest priority

Next is   N with molecular weight(14.0067 u) implies that - will  have the next priority

Next is   O with molecular weight(15.999 u) implies that will  have the next priority

The Last is  H with molecular weight(1.00784 u) implies that   will  have the next priority
