Chapter 16.2, Problem 16.2PP

Interpretation Introduction

(a)

Interpretation:

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

  

Concept Introduction:

In organic chemistry, IUPAC naming is a systematic method of naming organic molecules. The IUPAC is termed as the International Union of Pure and Applied Chemistry, which makes the set of rules for naming the molecules in chemistry. IUPAC naming is sometimes easier than the older name, such that ethanol is IUPAC name and ethyl alcohol is older name.

A carbonyl group is a group composed of carbon and oxygen atoms, which are double-bonded to each other. Any compound comprising aldehyde group is termed as a carbonyl molecule. In organic chemistry, there are various carbonyl compounds, such as aldehyde, ketone, carboxylic acid, carboxylate ester, and amide.

In order to give the name to the carbonyl compound following steps are followed:

1. The parent (longest) continuous carbon chain containing a carbonyl group (=CO) is selected.

2. While writing the name of aldehyde, the suffix "e" of the corresponding alkane is replaced by "-al", and while writing the name of ketone, the suffix "e" of the corresponding alkane is replaced by "-one"

3. Name should be written in alphabetical order and numbering should be done in such a way that the multiple bond and substituent group gets the lowest number.

4. Hyphen is used to connect the number to the name.

For number of carbons atoms in alkane chain, the prefix is given as:

Carbon-1 meth

Carbon-2 eth

Carbon-3 prop

Carbon-4 but

Carbon-5 pent

Carbon-6 hex

Carbon-7 hept

Carbon-8 oct

Carbon-9 non

Carbon-10 dec
