Chapter 22.1, Problem 1PP

Interpretation Introduction

Interpretation:

The name of the given alkyl halide needs to be determined.

Concept introduction:

The organic compounds generally contain carbon atoms. The naming of organic compounds is done by considering three main terms which are prefix, suffix and the root name. The longest chain in the compound is first identified and named that will be the root name for the compound. For example, if there are 3 carbon atoms in the longest chain, the root name will be “prop”. To determine the suffix, functional group should be identified. For example, alcohol group will have suffix −ol, aldehyde will have suffix −al. If there is no functional group the suffix will be −ane. In the last step, side groups are identified and named. Prefix is used to give number of side groups and substituent’s present on the main carbon chain.

Answer to Problem 1PP

2, 3-difluorobutane.

Explanation of Solution

The given organic compound is as follows:

It is an alkyl halide with 4 number of carbon atoms. Thus, the root name will be “But”. The naming of carbon atoms is done as follows:

There are 2 fluorine (halide) atoms, one each at 2^nd and 3^rd positions in the main chain. The name of the compound will be 2, 3-difluorobutane.

Conclusion

Thus, the name of the given compound is 2, 3-difluorobutane.
