Chapter 23, Problem 13STP

Interpretation Introduction

Interpretation:

Whether the name of the compound is correct or not needs to be determined.

Concept introduction:

Structural formula of a molecule is determined by considering the longest carbon chain first and then by naming the substituents attached to this chain.

Answer to Problem 13STP

Yes, the name of the compound given by the student is correct.

Explanation of Solution

The given structure is,

We can do the numbering of this structure as follows,

The longest chain in this molecule has 5 carbon atoms. Therefore, it is a pentane. Carbon-2 is attached with an ethene molecule and carbon-3 has two methyl groups.

So, the name of the structure is 2-ethyl-3, 3-dimethyl pentane. Therefore, the name given by the student is correct.

Conclusion

The name given by the student 2-ethyl-3, 3-dimethyl pentane is correct.
