Interpretation Introduction

Interpretation:

Name of the compounds given in the problem statement has to be given.

Concept Introduction:

A common nomenclature of naming organic compounds has been developed by IUPAC. By usage of this nomenclature or rules, memorizing of names of organic compounds is not necessary.

IUPAC rules for naming alkanes:

There are about five rules that has to be followed for naming an alkane and they are,

The longest continuous carbon chain in the compound has to be identified. This is known as parent compound. From this the parent name is obtained. Suffix “–ane” (for alkane) is added at the end of the prefix which gives information about the number of carbon atoms.

Numbering has to be done so that the lowest number is given to the first group that is encountered in the parent chain.

Naming and numbering has to be given for each atom or group that is attached to the parent chain. Numbering has to be done in a way that substituents get the least numbering.

If the same substitution is present in the parent chain more than once, a separate prefix is added which tells about the number of times the substituent occurs. Prefixes used are di-, tri-, tetra-, penta- etc.

Name of the substituents has to be placed in an alphabetical order before the parent compound name.

Part II. two unbranched ketone have molecular formulla (C8H100). El-ms showed that both of them have a molecular ion peak at m/2 =128. However ketone (A) has a fragment peak at m/2 = 99 and 72 while ketone (B) snowed a fragment peak at m/2 = 113 and 58. 9) Propose the most plausible structures for both ketones b) Explain how you arrived at your conclusion by drawing the Structures of the distinguishing fragments for each ketone, including their fragmentation mechanisms.
