SUMMARY

The structure in question is named isopropyl-2-chlorobenzoate, indicating that the isopropyl group is the principal substituent while the chloro group is attached to the benzene ring at the second carbon. The naming convention prioritizes the isopropyl group over the chloro group, which is why it is placed first in the name. The confusion arises from the potential ambiguity in the alternative name, 2-chloroisopropylbenzoate, which does not clarify the attachment of the chlorine substituent. This distinction is crucial for accurately conveying the structure's composition.

PREREQUISITES
  • Understanding of organic chemistry nomenclature
  • Familiarity with substituent priority rules in IUPAC naming
  • Knowledge of functional groups, specifically carboxylic acids and their derivatives
  • Basic comprehension of benzene derivatives and their structures
NEXT STEPS
  • Study IUPAC naming conventions for organic compounds
  • Learn about substituent priority in organic chemistry
  • Explore the properties of benzoate derivatives
  • Investigate the structural representation of organic compounds using molecular models
USEFUL FOR

Chemistry students, organic chemists, and anyone involved in the study or application of organic compound nomenclature.

The Attempt at a Solution



i understand that benzoate is derived from carboxylic acid (COOH) to which isopropyl has replaced the H, forming a benzoate substituent to which we derive the parent name of the structure. I understand that Chloro is the name for the Cl substituent and that it is joined to C2. What i don't understand is why the structure is called:

isopropyl-2-chlorobenzoate

as opposed to

2-chloroisopropylbenzoate

does it possibly have something to do with the fact that 2-chloroisopropylbenzoate does not specify whether the Cl substituent is joined to C2 on isopropyl or benzene? Or does the isopropyl group take priority over the Cl group?

isopropyl-2-chlorobenzoate isn't alphabetised and that's what confuses me the most here.

Not quite sure and in need of a little help. Thankyou.

That would be my understanding - chloroisopropyl suggests to me chlorine attached to isopropyl, not to the benzene ring.
