Hello, everyone. Today we have the following problem. Write the name of the amine shown. So in naming amines, we first want to identify any alkyl groups that are attached to the nitrogen atom. We see here that we have one methyl. There, we have an ethyl carb, an ethyl group as composed of two carbons. And then we have a pencil group as it is composed of five carbons. We then named the alco groups alphabetically as substituents. So between the E and ethyl M and methyl and P and pencil, the ethyl would come first. So we would have ethyl followed by the methyl because M and methyl comes before the P and pencil and then we would lastly have pencil and then we always end the naming of amines with amine. And it's also important to note that we do not include spaces between the last substituent and the Aming name. And with that, we have solved the problem overall, I hope it helped. And until next time.

Name each amine
c.

Verified step by step guidance

Identify the structure of the amine by examining the carbon chain and the nitrogen atom.

Determine the longest carbon chain attached to the nitrogen atom to identify the parent name.

Count the number of carbon atoms in the longest chain to determine the appropriate alkane name (e.g., methane, ethane, propane, etc.).

Identify and name any substituents or branches attached to the main carbon chain, including their position on the chain.

Combine the names of the substituents with the parent amine name, ensuring to use the correct numbering and prefixes (e.g., N-methyl, N,N-dimethyl) to indicate the position and number of substituents.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Amines

Amines are organic compounds derived from ammonia (NH3) by replacing one or more hydrogen atoms with alkyl or aryl groups. They can be classified as primary, secondary, or tertiary based on the number of carbon-containing groups attached to the nitrogen atom. Understanding the structure of amines is crucial for naming them correctly.

Nomenclature of Organic Compounds

The nomenclature of organic compounds follows specific rules set by the International Union of Pure and Applied Chemistry (IUPAC). For amines, the naming involves identifying the longest carbon chain attached to the nitrogen and using suffixes or prefixes to denote the presence of the amine functional group. Familiarity with these rules is essential for accurately naming amines.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the case of amines, the amino group (-NH2) is the functional group that defines their chemical behavior. Recognizing functional groups helps in understanding the reactivity and properties of organic compounds.
