Why nitro tautomer is more stable than its aci nitro tautomer in tautomerism?
The nitro tautomer is more stable than its aci nitro tautomer primarily due to resonance stabilization. In the nitro form, the negative charge is delocalized over the electronegative nitrogen atom and the adjacent oxygen atoms, leading to a more stable electronic configuration. In contrast, the aci nitro tautomer has a less favorable charge distribution and is less resonance-stabilized, making it energetically less favorable. Additionally, the hydrogen atom in the aci tautomer can lead to increased steric strain, further contributing to its instability.

How is hypophosphous acid?
H3PO2 a phosphorus oxoacidand a powerful reducing agent, HOP(O)H2 exists in equilibrium with the minor tautomer HP(OH)2
Is uric acid alkaline or acidic?
Acidic. It forms a tautomer in which the oxygen atoms bond with the H atoms of the NH in the ring. The hydrogen atoms can then be easily donated. Under the Bronsted-Lowry theory of acids and bases, a hydrogen donor is classified as an acid.

What is ethynol?
It is a molecular compound with formula C2H2O. Writing it in order of the atoms in the molecule it would be H-C-C-O-H. There is a tripe bond between the two carbon atoms. Most compounds with an -OH attached to a double- or triple-bounded carbon are very unstable. Ethynol, if produced, would be immediately converted to its tautomer, H2C=C=O, or ketene, which itself is highly reactive and prone to polymerization.
What is hypoxanthine?
Hypoxanthine is a naturally occurring purine derivative. It is occasionally found as a constituent of nucleic acids, where it is present in the anticodon of tRNA in the form of its nucleoside inosine. It has a tautomer known as 6-hydroxypurine. Hypoxanthine is a necessary additive in certain cell, bacteria, and parasite cultures as a substrate and nitrogen source. Hypoxanthine is also a spontaneous deamination product of adenine. Because of its resemblance to guanine, the spontaneous deamination of adenine can lead to an error in DNA transcription/replication.
What is tautomerism?
Tautomerism refers to an equilibrium between two different structure of the same compound. Usually the tautomers differ in the point of attachment of a hydrogen atom.Tautomers are two forms of a compound that interconvert by a process known as tautomerization. A common type of tautomer is found with ketones. This is called keto-enol tautomerism. The ketone and its enol form are readily interconvertible constitutional isomers that exist in equilibrium with each other. Isomers that differ from each other only in the location of a hydrogen atom and a double bond are proton isomers. Proton tautomers are isomers in which a hydrogen atom and a double bond switch locations between a carbon atom and a heteroatom (which is an atom other than carbon, such as oxygen or nitrogen). There is a rule which states, called Erlenmeyer Rule, which states that all alcohols in which the hydroxyl group is attached directly to a double-bonded carbon atom become aldehydes or ketones. This occurs because the keto form is generally more stable than its enol tautomer. Tautomers differ from each other in locations of atoms as well as electrons, and so are NOT resonance contributors, which are different representations of the same structure.See the Web Links to the left for some diagrams of molecules with are tautomers for a better understanding and more information.

Does C2H4O represent aldehyde?
No. Or, at least, it doesn't exclusively represent "aldehyde", whatever you mean by that.An aldehyde is a compound containing the moiety -CHO. C2H4O is the empirical formula for ethanal, which is an aldehyde. However, it's also the empirical formula for vinyl alcohol, which is not. It's somewhere between difficult and impossible to say much about a compound based purely on its empirical formula.
Do all molecules in a compound have to be the same?
Yes and no. All molecules of a compound will have the same chemical formula, but some compounds have isomeric forms where the molecules can have different structures/shapes. These isomeric forms do sometimes have different properties than the usual form of the compound (e.g. boiling point, freezing point, rotation of polarized light) but they are still the same compound.
