What functional group contributes a negative charge?
The carboxyl group (-COO-) contributes a negative charge by deprotonating to form a carboxylate ion (-COO-). This functional group is commonly found in amino acids and fatty acids.
A ketone bears a negative charge on what atom of the carbonyl group?
The carbon atom in the carbonyl group of a ketone does not bear a negative charge. The oxygen atom in the carbonyl group of a ketone bears a partial negative charge due to its higher electronegativity compared to carbon.
At Ph 10 what charge would Zwitterion ion have?
it would depend on amino acid in question. pH above amino acid pI, zwitterion will carry net negative (-) charge. at pH below pI, zwitterion will carry net positive (+) charge. depending on the amino acid, some have more than one acidic or basic functional group. such functional groups can make the amino acid vary in net charge from 2- to 2+ if not more.
What functional group causes a molecule of citric acid to be acidic?
The carboxylic acid functional group (-COOH) is what causes citric acid to be acidic. This group can donate a proton, which contributes to the acidity of the molecule.
How to determine the strongest acid among a group of compounds?
To determine the strongest acid among a group of compounds, you can compare their acidity based on their ability to donate a proton (H ion). The compound that can easily donate a proton and stabilize the resulting negative charge is considered the strongest acid. This can be determined by looking at the chemical structure and the presence of functional groups that can stabilize the negative charge.
What functional group contributes a negative charge?
The carboxyl group (-COO-) contributes a negative charge by deprotonating to form a carboxylate ion (-COO-). This functional group is commonly found in amino acids and fatty acids.
Is -OH an ion or a radical?
In the past -OH was considered a radical; now the recommended name is functional group.
A ketone bears a negative charge on what atom of the carbonyl group?
The carbon atom in the carbonyl group of a ketone does not bear a negative charge. The oxygen atom in the carbonyl group of a ketone bears a partial negative charge due to its higher electronegativity compared to carbon.
Why is polar convalent bonds important?
the higher the polarity on a functional group, the more reactive it is. If a functional group is non-polar, it doesn't react with anything without a LOT of energy.For example: a hydrophobic functional group would avoid water at all cost, because it is non-polar, whereas water is polar. Try not to think of this as a "likes repel" sort of thing, but rather that a non-polar functional group is one that has no charge on it, and a polar group has a (+) or (-) charge. While it is true that two (+)'s will repel each other, if there is a (+) functional group, there is likely a (-) one on the other side, which would cause the molecule to flip around and bond that way.Essentially, polarity of a functional group functions as the + or - charge used to bond to the opposite charge of another molecule/functional group.
At Ph 10 what charge would Zwitterion ion have?

Organice compounds that have a negative Oxygen Hydrogen functional group?
Organic compounds with an oxygen hydrogen functional group are either alcohols or carboxylic acids
What is the name of any atom or group of atoms with a negative charge?
An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
What functional group causes a molecule of citric acid to be acidic?
The carboxylic acid functional group (-COOH) is what causes citric acid to be acidic. This group can donate a proton, which contributes to the acidity of the molecule.

What is the charge of an acetyl group in a chemical compound?
The charge of an acetyl group in a chemical compound is neutral, meaning it has no overall positive or negative charge.
What functional group makes taurocholate water soluble?
The sulfate group (-SO3H) in taurocholate is responsible for making it water soluble. This group imparts a negative charge to the molecule, allowing it to interact with water molecules and dissolve in aqueous environments.
Does phosphatidylethanolamine and phosphatidylserine have negative charges?
Phosphatidylethanolamine does not have a negative charge, while phosphatidylserine does have a negative charge at physiological pH due to its carboxyl group.
