What functional group contributes negative charge?
The carboxyl group (-COO-) contributes a negative charge in a molecule due to the presence of the oxygen atoms, which tend to pull electrons toward them, resulting in a partially negative charge on the oxygen atoms.
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?
At pH 10, the zwitterion would have a net negative charge because the pH is higher than its isoelectric point (pI). The amino group would be deprotonated and have a negative charge, while the carboxyl group would still be protonated and neutral.
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 particles in the periodic table have a negative 1 charge?
Particles with a negative 1 charge in the periodic table are typically electrons or anions (ions with a negative charge).
What functional group contributes negative charge?
The carboxyl group (-COO-) contributes a negative charge in a molecule due to the presence of the oxygen atoms, which tend to pull electrons toward them, resulting in a partially negative charge on the oxygen atoms.
Is -OH an ion or a radical?
-OH is a functional group called hydroxyl group, commonly referred to as a radical in organic chemistry. It is not an ion because it does not carry a net positive or negative charge.
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.
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?
At pH 10, the zwitterion would have a net negative charge because the pH is higher than its isoelectric point (pI). The amino group would be deprotonated and have a negative charge, while the carboxyl group would still be protonated and neutral.
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 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 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 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.
What functional group in the DNA structure causes it to move only toward the positive poles?
The phosphate group in the DNA backbone has a negative charge due to its phosphate ions. This negative charge causes the DNA molecule to move towards the positive pole in processes such as gel electrophoresis.
Which part of a dna nucleotide contains a negative charge?
The DNA nucleotide consists of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The portion of the nucleotide that contains a negative charge is the phosphate group.
