Question

-CH2SH -OH -Cl -CH2OH arrange cahn-ingold-prelog rules starting with the highest priority

Answer 1

Increasing order of priority -CH2OH < -CH2SH < -OH < -Cl

Rules :

- A substituent with a higher atomic number takes precedence over a substituent with a lower atomic number.

- If there are two substituents with equal rank, proceed along the two substituent chains until there is a point of difference. First, determine which of the chains has the first connection to an atom with the highest priority (the highest atomic number). That chain has the higher priority.
