A student named an alkane 2- ethylpropane. Its correct IUPAC name is?
Verified Answer
A student named an alkane 2- ethylpropane. Its correct IUPAC name is?
If we draw the structure of the compound name the student gave, it will be
.. C2H5
... |
H3C - CH - CH3
As you can see, the longest chain is not three atoms, it is four atoms (the ethyl group and the rest of the chain).
So, its correct name will be 2-methyl butane.

A student named an alkane 2- ethylpropane. Its correct IUPAC name is?
Understanding the Incorrect Name: 2-Ethylpropane
The name "2-ethylpropane" suggests a structure that is not consistent with IUPAC naming conventions.
Breaking Down the Structure
- Propane indicates a 3-carbon straight chain (C-C-C).
- 2-Ethyl implies the presence of an ethyl group (C-C) attached to the second carbon of propane.
Identifying the Correct Structure
- When you consider the structure, 2-ethylpropane would imply a 5-carbon molecule:
- Propane (3 carbons) with an ethyl group (2 carbons) attached at the second carbon.
- This leads to the formation of a branched alkane.
Correct IUPAC Naming
- The correct structure is actually that of pentane, specifically 2-methylbutane:
- The main chain (longest carbon chain) contains 4 carbons (butane).
- An additional methyl group is attached to the second carbon.
Final Conclusion
- The correct IUPAC name for "2-ethylpropane" is 2-methylbutane.
- Naming alkanes requires identifying the longest carbon chain and substituents accurately to conform to IUPAC rules.
This clarification helps ensure precise communication in organic chemistry.
