Q15-2P - Organic Chemistry (Mcmurry)

Question

Give IUPAC names for the following compounds:

Step-by-Step Solution

Answer

IUPAC names of the given compounds are as follows

1. meta-Chloro bromo benzene
2. 3-methyl-1-phenyl butane
3. para-bromo aniline
4. ortho, para-dichloro toluene
5. ortho, para-dinitro ethylbenzene
6. ortho, meta, para-trimethyl toluene

Step 1: Naming of benzene substituted compounds

If more than one substituent is present in benzene ring then we named that benzene substituted compound with the help of some terms like ortho, meta , para.

Step 2: Naming of the given compound for part (a)

As in the given compound, two substituents are attached chlorine and bromine.

So, the position of chlorine with respect to bromine is meta.

Step 3: Naming of the given compound for part (b)

As in the given compound two substituents are attached one is benzene and another one is methyl in the chain of four carbon atoms

The name of the compound is 3-methyl-1-phenyl butane

Step 4: Naming of the given compound for part (c)

As in the given compound, two substituents are attached amine and bromine.

So the position of bromine with respect to amine is para

Step 5: Naming of the given compound for part (d)

As in the given compound, three substituents are attached two substituents are chlorine and the third is bromine.

Step 6: Naming of the given compound for part (e)

As in the given compound, three substituents are attached. Two substituents are nitro and the third is an ethyl group.

Step 7: Naming of the given compound for part (f)

As in the given compound, four substituents are attached. All are methyl groups

The name of the compound is ortho, meta, para-trimethyl toluene OR o,m,p-trimethyl toluene.
