Question

of the major product in each of the

following reaction.​

Answer 1

Answer:  The IUPAC name of the major product is

               a)1-Iodo-2-methyl propane

               b)1,1-difluoro-2-bromomethane

Explanation:

Numerous prefixes, suffixes, and infixes are employed in chemistry to specify the kind and location of the functional groups in a compound.

An organic compound is named using the following steps:

1)Identifying the hydrocarbon chain's progenitor. The following regulations must be followed by this chain, in order of importance:

• It ought to have as many substitutes for the suffix, and functional group, as possible. In contrast to halogen substituents, the parent functional group should have a suffix, which is what is meant by the term "suffix."
• If there are many functional groups, use the one with the highest group precedence.

• The greatest amount of multiple bonds should be present.

• It should be as long as possible.

• The greatest number of branches or substitutes should be listed as prefixes.

• The greatest number of single bonds should be present.

2)Identifying the functional group with the highest precedence, if any, as the parent functional group.

3)The side chains' identification The carbon chains that branch off from the parent chain and are not part of the parent chain are known as side chains.

4)If any functional groups are left, they should be identified and given ionic prefixes

5)We will alphabetically group various side chains and functional categories. (Alphabetical grouping does not take the prefixes di-, tri-, etc. into account. For instance, the "e" in "ethyl" comes before the "h" in "dihydroxy" and the "m" in "dimethyl" alphabetically, thus it comes before dihydroxy or dimethyl. The "di" neither situation is taken into account). It is preferable to write side chains and secondary functional groups mixed in one group rather than two separate groups when both are present.

6)Recognizing double and triple bonds.

7)A chain's numbering system. To accomplish this, number the chain in both directions (left to right and right to left) first, and then select the numbering that adheres to these guidelines, in order of priority.

8)Has the locant (or locants) with the lowest number for the suffix functional group. The numbers on the carbons that the substituent is directly bonded to are called locants.
