Answer to Problem 24PP

  • Name for the given compound

            Organic Chemistry, Chapter 17, Problem 24PP , additional homework tip  1

             4-ethylbenzoic acid

Explanation of Solution

  4-ethylbenzoic acid

From the structure of the compound it is clear that the parent group is benzoic acid.

The second step to name the structure of the polysubstituted benzene ring is

Identification of substituent and its locant at the lowest possible number, for the given compound an ethyl group is a substituent and it is placed to the 4th ( C4 ) position of benzoic acid. So for naming the compound, name of substituent with locant by an alphabetic order should be assigned firstly and the name of the parent will become at the end. So the given compound name is 4-ethylbenzoic acid

      2-bromophenol

Explanation of Solution

The given compound b2-bromophenol

From the structure of the compound it is clear that the parent group is phenol.

The second step to name the structure of the polysubstituted benzene ring is

Identification of substituent and its locant at the lowest possible number. For the given compound bromine atom is a substituent and they are placed to the 2nd ( C2 ) position of phenol. So for naming the compound, name of substituent with locant by an alphabetic order should be assigned firstly and the name of the parent will become at the end. So the given compound name is 2-bromophenol

       2-chloro-4-nitrophenol

Explanation of Solution

The given compound c

2-chloro-4-nitrophenol

From the structure of the compound it is clear that the parent group is phenol.

The second step to name the structure of the polysubstituted benzene ring is

Identification of substituent and its locant at the lowest possible number. For the given compound a chlorine atom and nitro group are substituent and they are placed to the 2nd ( C2 ) and 4th ( C4 ) positions of phenol respectively. So for naming the compound, name of substituent with locant by an alphabetic order should be assigned firstly and the name of the parent will become at the end. So the given compound name is 2-chloro-4-nitrophenol

    2-bromo-5-nitrobenzaldehyde

Explanation of Solution

The given compound d

2-bromo-5-nitrobenzaldehyde

From the structure of the compound it is clear that the parent group is benzaldehyde.

The second step to name the structure of the polysubstituted benzene ring is

Identification of substituent and its locant at the lowest possible number. For the given compound a bromine atom and nitro group are substituent and they are placed to the 2nd ( C2 ) and 5th ( C5 ) positions of benzaldehyde respectively. So for naming the compound, name of substituent with locant by an alphabetic order should be assigned firstly and the name of the parent will become at the end. So the given compound name is 2-bromo-5-nitrobenzaldehyde

  • Organic Chemistry, Chapter 17, Problem 24PP , additional homework tip  5

    1, 4-diisopropylbenzene

Explanation of Solution

The given compound e

1, 4-diisopropylbenzene

From the structure of the compound it is clear that the parent group is benzene.

The second step to name the structure of the polysubstituted benzene ring is

Identification of substituent and its locant at the lowest possible number. For the given compound there are two substituents, both isopropyl group it is placed to the 1st ( C1 ) and 4th ( C4 ) positions of   benzene. So for naming the compound, name of substituent with locant by an alphabetic order should be assigned firstly and the name of the parent will become at the end. So the given compound name is 2-chloro-4-nitrophenol
