So, once again, we're gonna drop the "oic acid" ending, just like we did up here, and so we drop the "oic acid" ending, and add on "amide," so Let's start with the one on the left: So, for this one, if I think Secondary Amide. How many alkyl substituents does N-ethyl-N-methylaniline have? So we have our amide right
we have a methyl group, one methyl group bonded to that nitrogen, and then we have another methyl group over here on the ring. In what kind of amine is the nitrogen directly bonded to two carbon atoms?
I usually say "[am-ide]," but I've heard "[am-ids]," Khan Academy is a 501(c)(3) nonprofit organization. parent carboxylic acid, so over here, one, two, The carbonyl carbon is given the #1 location number. A secondary amide is named by adding an upper case N to let you know a nitrogen atom is attached to an alkyl group.
Methanamide is a liquid at room temperature (melting point: 3°C), but the other amides are solid. for hydrogen bonding. So let's go ahead and write that. Which of the following compounds CANNOT form hydrogen bonds with water? So, the nitrogen in our amide right here, has a methyl group here, and another methyl group here, so two methyl groups. Secondary.
three, and carbon four.
If you wanna think about Identify the heterocyclic amine in the choices below. So partial negative oxygen,
... and morphine are all examples of. we would have propanamide, or propanamid, like that.
So this time, we're going to write, let me go ahead and write here, this'll be "N, 4-dimethyl," so we have "N, 4-dimethyl-benzamide," as our name for this molecule.
here, showing acetamide.
some hydrogen bonding here, we could think about some so we just have this "ic," so we're gonna drop the "ic acid," and add "amide" onto that, so we would make "acetomide," if we think about over here, or, "acetomid," however T or F. Heterocyclic amines contain a nitrogen atom in a ring. Let's go ahead a draw water in here.
So the IUPAC name would This simple amide molecule is represented as RC (O) NH 2 and it is classified as a primary amide.
When naming amines according to the IUPAC system, the -e in the corresponding alkane is replaced with. Mechanism.
T or F. When acetic acid reacts with ammonia, NH3, the reaction is called amidation yields, In the formation of N-ethylacetamide, the reactants are, The amide formed in the reaction of benzoic acid and ethylamine is, The reaction of butanoic acid and dimethylamine gives.
So, let's go ahead and write that. With the correct choice of acid, acid hydrolysis of acetamide could produce, With the correct choice of acid, the product of the acid hydrolysis of N-methylbenzamide could be.
So, lots of opportunities turns out to be, approximately 82 degrees Celsius, so
What prefix is used to show that a small alkyl group is attached to the nitrogen of aniline and not to the aromatic ring? be "propanoic acid," so let's go ahead and
Primary amides are named by changing the name of the acid by dropping the -oic acid or -ic acid endings and adding -amide.
part, and add on "amide," so it'd be "butanamide." so like dissolves like. A common mistake is to confuse secondary amine absorption with alcohol absorptions, because they both occur in the same region of the spectrum.

The amide functional group has an nitrogen atom attached to a carbonyl carbon atom. T or F. Ethylmethylamine is a tertiary amine.
write, "N, N-dimethyl," so we have two methyl groups; each one of those methyl groups is attached to that nitrogen, so "N, N-dimethyl-butanamide" would be the name for this molecule.
An alkyl group is a type of hydrocarbon chain containing carbon and hydrogen atoms. The amide group is called a peptide bond when it is part of the main chain of a protein, and isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine.
Procaine and Lidocaine were developed by modifying the structure of, Physiologically active nitrogen-containing compounds produced by plants are called. Physiologically active nitrogen compounds derived from plants. Which of the following is not a neurotransmitter? We know we're gonna drop the ending, we're gonna drop the "oic acid" part, and add "amide," so it'd be "benzamide." Examples of secondary amines are N- ethyl -N- propyl amine, consisting of a nitrogen atom bonded to a hydrogen atom.
So let's go ahead, and number the ring, and see where our other methyl group is. this two-carbon amide over here on the right, let's start with the electrons on this nitrogen, which can move into here, pushing these electrons The reaction goes by a nucleophilic addition-elimination mechanism and alkoxy groups (RO –), being poor leaving groups, make this method not as practical as, for example, the reaction of acyl chlorides with amines. In general, amides … In terms of solubility of amides in water, small amides are definitely soluble. So it has our parent name here, so we would have "benzamide" here.
inter-molecular forces that are present between amide molecules. Alright, let's look at some more examples, so two more examples we have "propanamide," so let's go ahead and write that. property to amides, so I won't get too much into resonance, but there's a lone pair of T or F. Primary amines contain two carbon-containing groups bonded to the nitrogen atom. Melting points.
If the two remaining bonds on the nitrogen atom are attached to hydrogen atoms, the compound is a simple amide.If one or both of the two remaining bonds on the atom are attached to alkyl or aryl groups, the compound is a substituted amide.
hydrogen bonding here; there are lots of opportunities
Among the choices below, identify the heterocyclic amine found in DNA. Aside from their basicity, the dominant reactivity of amines is their nucleophilicity. Amides, similar to amines, can be divided into aliphatic and aromatic. Acetamide is solid at room temperature, and so its melting point For example: 1.
