What is the IUPAC name for the compound shown below? The name should have the format alkanamine. What is the IUPAC name for the compound shown below?
Answer
General guidance
IUPAC stands as international union of pure and applied chemistry. The IUPAC nomenclature has been used to identify organic compounds. The IUPAC name is composed of three parts: the root name, suffix and prefix.
An IUPAC name is made up of three parts: root name, suffix and prefix.
The root name is given by the longest chain.
Prefix indicates the name and position of substitutions on the longest chain.
The suffix indicates the functional group in the structure.
Step-by-step
Step 1 from 12
1.
Below is the structure of the compound.
ethan is the root name.
Common mistakes
The longest chain contains two carbon atoms. ethan is the root name of the given structure. Choose the longest chain so that the substituents have the lowest numbers.
Step 2 from 12
The nitrogen atom is attached to the methyl group.
The prefix Nmethyl
The nitrogen atom is attached to one methyl group. Nmethyl is the prefix.
Step 3 from 12
amine is the suffix
The IUPAC name for the given structure is Nmethylethanamine.
Explanation
The functional group is amine. amine is the suffix.
[Hint: For the next step]
Choose the longest chain within the given structure.
Step 4 from 12
2.
Below is the structure of the compound.
cyclopent is the root name.
Common mistakes
The longest chain contains five carbon atoms, and is in cyclic mode. cyclopent is the root name of the given structure. Choose the longest chain so that the substituents have the lowest numbers.
Step 5 from 12
At C-1 and C-2 carbons, two methyl groups can be substituted.
The prefix 1,2-dimethyl
At C-1 and C-2 carbons, two methyl groups can be substituted. 1,2-dimethyl is the prefix.
Step 6 from 12
The suffix is
Thus, the IUPAC name of the given structure is 1,2-dimethylcyclopentane
Explanation
Alkane is the functional group. The suffix is
[Hint: For the next step]
Choose the longest chain within the given structure.
Step 7 from 12
3.
Below is the structure of the compound.
pent is the root name.
Common mistakes
Five carbon atoms make up the longest chain. pent is the root name of the given structure. Choose the longest chain so that the substituents have the lowest numbers.
Step 8 from 12
At C-2 carbons, two methyl groups can be substituted for one ethyl group and one at C-3 carbon.
The prefix 3-ethyl-2.2-dimethyl is the one that you will see.
Explanation
One ethyl group is substituted for C-2 carbon, and two methyl groups are substituted for C-2 carbon. So, the prefix is 3-ethyl-2,2-dimethyl.
[Common mistake]
You must ensure that substitutes are named alphabetically.
Step 9 from 12
The suffix is
Thus, the IUPAC name of the given structure is 3-ethyl-2,2-dimethylpentane
Explanation
Alkane is the functional group. The suffix is
[Hint: For the next step]
Choose the longest chain within the given structure.
Step 10 from 12
4.
Below is the structure of the compound.
cyclohexan is the root name.
Common mistakes
The longest chain contains six carbon atoms, and is in cyclic mode. cyclohexan is the root name of the given structure. Choose the longest chain so that the substituents have the lowest numbers.
Step 11 from 12
There are no substitutes.
The prefix is absent
Explanation
There are no substituents. is the prefix.
Step 12 from 12
The IUPAC name for the given structure is cyclohexanol.
Explanation
Alcohol is the functional group. The suffix is.
Answer
The IUPAC name for the given structure is Nmethylethanamine.
Thus, the IUPAC name of the given structure is 1,2-dimethylcyclopentane
Thus, the IUPAC name of the given structure is 3-ethyl-2,2-dimethylpentane
The IUPAC name for the given structure is cyclohexanol.
Only answer
The IUPAC name for the given structure is Nmethylethanamine.
Thus, the IUPAC name of the given structure is 1,2-dimethylcyclopentane
Thus, the IUPAC name of the given structure is 3-ethyl-2,2-dimethylpentane
The IUPAC name for the given structure is cyclohexanol.
Conclusion
Above is the solution for “What is the IUPAC name for the compound shown below? The name should have the format alkanamine“. We hope that you find a good answer and gain the knowledge about this topic of science.
