What is OH in chemistry?
OH- (note the negative charge) is the hydroxide ion. This ion consists of a deprotonated water molecule; it acts as a base. OH (typically denoted ROH) can also denote a hydroxyl group, which is a common functional group in organic chemistry. For example MeOH is methanol, CH3OH.
Why the oxygen of a hydroxyl group act as a nucleophile or a base?
The hydroxyl group is the common denomination for a molecule consisting of an oxygen and a hydrogen atom connected by a covalent bond, in other words a O-H, where the oxygen atom has two or three (in case its an hydroxide anion) pair of free electrons, which can attack another atom with a deficiency of electrons and make a bond (acting like a nucleophile) or the same thing but attacking a proton H+ (atom with deficiency of electrons) acting in this case as a base. In both cases it acts as a nucleophile but when it attacks a proton or a molecule with a proton (like an acid) acts specifically as a base. I hope I could answer your question.
What does OH mean in science?
There is no such chemical symbol. 'OH' does not exist as a substance. However, the symbol 'OH^-' does exist, it is the symbol for the hydroxide anion(ion). Further when 'OH^-' is shown in a substance , e.g. NaOH , the 'OH^- ,moiety still exists but is cancelled out by the 'Na^+' Two equal and opposite charges.
What functional group does a nucleotide contain?
Hydroxyl-OH Amino-NH2 Phosphate-PO4
What is R-CH3?
R-CH3 is an organic composite obtained starting from methane (CH4) and substituting one of the hydrogen atoms with an organic radical, generally indicated with R. Frequently the functional group -CH3 is also called methil group. Important examples are acetic acid, where R is the acid group COOH, so that the acetic acid has molecular formula CH3COOH and the methanamine, where the functional group is the amine group (NH2) so that the molecular formula results to be CH3NH2.
Why tertiary hydroxyl group protection is difficult?
ascorbic acid hydroxyl group protection
What is --COOH?
It is a carboxyl functional group, consisting of a carbonyl and hydroxyl group. It is an ACID [moiety].
How does a hydroxyl group differ from a carboxyl group?
The hydroxyl group is an amino group and the carboxyl group is an amino acid that was one of my science questions and thats the best answer i could find. hope this helps
Why tartaric acid not give phenolphthalein test?
because of hydroxyl group
What functional groups act as an acid?
two examples are carboxyl and hydroxyl examples are vinegar for carboxyl and phenol for hydroxyl there are many others
What is ester bond?
Ester bond is formed when the carboxyl group of fatty acid combine with the hydroxyl group of glycerol.
Is serine polar?
Yes serine is a polar amino acid as it has an hydroxyl group (OH-) attached to the r group.
What is alpha hydroxy acid?
An alpha hydroxy acid is a carboxylic acid having a hydroxyl group substituted to the adjacent carbon (ex. glycolic acid -OHCH2COOH.
What is an arachidonoyl?
An arachidonoyl is a univalent radical formally derived from arachidic acid by removal of the hydroxyl group.
Does the functional group react differently depending on the carbon backbone?
A functional group may react differently, but does not always do so. One of the well known examples is a hydroxyl group, which ionizes sufficiently to act as a weak acid when the hydroxyl group is bonded directly to a carbon atom that is part of an aromatic ring, but not when the hydroxyl group is attached to a carbon that is part of an aliphatic chain.
What is -OH group?
The -OH group is called the hydroxyl group
What are the organic compounds that have an -OH functional group?
Alcohols and phenols (hydroxyl functional group)
