chem2750 special assignment 2 (10 points) name name the following compounds

Answer

Explanation:

Step1: Identify functional - groups

For each compound, first identify the main functional - groups such as carbonyls (ketones, aldehydes, esters, amides), halides, nitro - groups, etc.

Step2: Determine the parent chain

Find the longest carbon - chain that contains the main functional group.

Step3: Number the carbon atoms

Number the carbon atoms in the parent chain starting from the end closest to the main functional group.

Step4: Name substituents

Name the substituents (such as alkyl groups, halogens, nitro - groups) and assign them numbers according to their position on the parent chain.

Step5: Combine names

Combine the names of the substituents, the parent - chain name, and the name of the main functional group to get the full name of the compound.
