according to Cahn-ingold-prelog sequence rules​

Answer 1

Answer:

In following groups there are the highest priority from the can - ingold- prelog- sequence rules.Is the highest priority from the groups

Answer 2

According to Cahn-Ingold-Prelog sequence rules,​ the highest priority group will be the central carbon atom.

Explanation:

• According to the Cahn-Ingold-Prelog sequence rule -It says that the "Atom or the atoms present in the group having the highest atomic number which is directly adjoined with the central carbon atom is considered as the highest priority group."
• When we compare the atomic number (Z) of any atoms directly attached to the stereocenter it will be the group having the atom of higher atomic number which receives higher priority.
• So $-CH2Cl$ will have the highest priority as per the rule.
