As mentioned, a large part of the action caused by the hydroxyl group is due to the electronegativity of the oxygen.
A vicinal diol has two hydroxyl groups on same carbon atoms. True.
These compounds are called glycols. So, it is the correct answer.
Sodium is not a functional group and it is an unstable alkali metal. hemiacetal Two functional groups attached to the same carbon. This substance is unstable, as it has two hydroxyl groups on the same carbon atom. Additionally the deoxyribose sugar in DNA is much less reactive than the ribose sugar in RNA.
On the other hand, important biomolecules can be modified by the introduction of oxygen atoms by means of non-oxidative hydroxyl radicals.
2-methylpropan-2-ol is a tertiary alcohol. The primary reason involves the relative stability of the two molecules.DNA is more chemically stable than RNA because it lacks the hydroxyl group on the 2' carbon. What functional groups define the two different ends of a DNA strand?
organic-chemistry nomenclature carbonyl-compounds. I think it is hydroxymethanoic acid, but I am not completely sure.
A geminal diol has two hydroxyl groups bonded to the same atom. Weekly acidic. Ask for details ; Follow Report by Jaindrasingh3229 27.10.2018 Log in to add a comment - 15586451 Another example is (F 3 C) 2 C(OH) 2, the hydrated form of hexafluoroacetone. Explanation for the correct answer: Option (b) is given as hydroxyl. So, I doubt this would even exist. This will normally mean that the hydroxyl group is joined to the same carbon atom as a branch. B. Answer. Maybe the two hydroxyls are on neighbour atoms (such as 2 and 3). Usually unstable. Acetals are products of substitution reactions catalyzed by acid. Formed from reaction between an alcohol and an aldehyde or ketone. November 22, 2019 Musaf Karkera.
A.
Besides these two large classes of molecules that are functionally dependent on the hydroxyl group, many other molecules contain hydroxyl groups.
However, clinical trials with such antioxidants as ascorbic acid and vitamin E, failed to produce the expected beneficial results. And the final compound that I am not sure about is when there are two hydroxyl groups attached to the carbon as well as an oxygen with a double bond. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H 2 C(OH) 2.
This kind of compounds automatically transform into ketones, releasing one molecule of water. Mixing the two reactants together produces the hemiacetal.
The compounds in which two or three hydroxyl groups are attached to the same carbon atom are unstable and lose water to give aldehydes, ketones, or carboxylic acids. False.
These species arise by hydration of the carbonyl compounds.
Because of that hydroxyl group on the 2' carbon sugar ... Nucleic acids are directional, meaning that there are two different ends. D. None of the above.
Very weekly acidic.
carbon atom. It’s an alkene and an alcohol. Note : If two or more hydroxyl groups attached to same carbon atom, the compound is usually unstable and lose a molecule of water to give a stable and therefore two or more hydroxyl groups must be present on different carbon atoms.
Why is RNA more reactive and unstable than DNA: Definition. explain why alcohols having two or more hydroxy group on the same carbon atom is extremely unstable and immadietly loses water molecules - Chemistry - TopperLearning.com | 5trpdw66 phenol -OH directly bonded to an aromatic ring.
