Chapter 23, Problem 11STP

Interpretation Introduction

Interpretation:

The IUPAC name of the given organic compound needs to be determined.

Concept introduction:

For IUPAC naming of a compound we count the longest carbon atoms and then number all the carbon atoms in the longest chain. The number of the carbon atom to which a substituent is attached is noted down for further naming of the compound.

Answer to Problem 11STP

The IUPAC name of the given organic compound is 2, 3-dibromo-4-chloro-5-fluoropentane.

Explanation of Solution

The given organic compound is,

The longest carbon chain has 5 carbon atoms. Br is attached to carbon-3, Cl is attached to carbon-4 and F is attached to carbon-5. For Br, Cl and F we use the prefixes bromo-, chloro- and fluoro- respectively.

So, the IUPAC name of the given compound is 2, 3-dibromo-4-chloro-5-fluoropentane.

Conclusion

2, 3-dibromo-4-chloro-5-fluoropentane is the IUPAC name of the given organic compound.
