Which of the following is example of triazine?
Which of the following is example of triazine?
A well known triazine is melamine (2,4,6-triamino-1,3,5-triazine). With three amino substituents, melamine is a precursor to commercial resins. Guanamines are closely related to melamine, except with one amino substituent replaced by an organic group.
What is the use of triazines?
Triazine is a prototypal molecule that has together with its derivatives wide commercial use, for example, in resins, dyes, herbicides, or as sulfide removal agents.
Is c3h3n3 aromatic?
The chemical compound 1,3,5-triazine, also called s-triazine, is an organic chemical compound whose chemical structure has a six-membered heterocyclic aromatic ring consisting of three carbon atoms and three nitrogen atoms.
What is triazine skeleton?
Definition. Any compound with a 1,3,5-triazine skeleton, in which nitrogen atoms replace carbon at positions 1, 3 and 5 of the core benzene ring structure. Stars. This entity has been manually annotated by the ChEBI Team.
Is Pyrazine basic?
Pyrazine is a heterocyclic aromatic organic compound with the chemical formula C4H4N2. Pyrazine is less basic than pyridine, pyridazine and pyrimidine. Pyrazine and a variety of alkylpyrazines are flavor and aroma compounds found in baked and roasted goods.
Is triazine a functional group?
Triazenes are a class of organic compounds containing the functional group -N(H)-N=N-. Triazene, possibly along with its isomer triimide (HNNHNH), has been synthesized in electron-irradiated ices of ammonia and ammonia/dinitrogen and detected in the gas phase after sublimation.
How do you make atrazine?
Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropyl amine. Like other triazine herbicides, atrazine functions by binding to the plastoquinone-binding protein in photosystem II, which animals lack.
Which one is triazine group of herbicide?
Some triazine herbicides are listed below: Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) Propazine. Simazine (2-chloro-4,6-bis-ethylamino-1,3,5-triazine)
Why is thiazole aromatic?
The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current.
Is pyridazine basic?
Pyridazines (also known as 1,2-diazine, orthodiazine, or oizine) are six-membered heterocylic aromatic organic compounds with two nitrogen atoms which are adjacent to each other. The diazines are essentially mono-basic substances and weaker bases than pyridine.
Is pyrazine a diazine?
Pyrazine is a heterocyclic aromatic organic compound with the chemical formula C4H4N2….CHEBI:30953 – pyrazine.
| ChEBI Name | pyrazine |
|---|---|
| Definition | A diazine that is benzene in which the carbon atoms at positions 1 and 4 have been replaced by nitrogen atoms. |
Where does the nitrogen in urea-triazone come from?
Urea-triazone nitrogen (N) is a stable solution resulting from a controlled reaction in aqueous medium of urea, formaldehyde, and ammonia which contains at least 25% total N. This N source contains no more than 40%, nor less than 5%, of total N from unreacted urea and not less that 40% from triazone.
What are the two types of nitrogenous bases?
A nitrogenous base is simply a molecule that contains nitrogen and has the chemical properties of a base. There are two kinds of nitrogenous bases present in DNA and RNA: pyrimidine bases and purine bases.
What are the names of the nitrogen atoms in deoxyribose?
The carbon atoms present in the deoxyribose are numbered 1’, 2’, 3’, 4’ and 5’. Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1’ of deoxyribose through a glycosidic bond.
What makes thymine and cytosine nitrogenous bases?
Cytosine and thymine are both pyrimidine bases. Cytosine starts out as the single ring pyrimidine, and an extra oxygen, nitrogen and three hydrogen atoms are attached to the ring. Cytosine is very unstable, and can change form if left on its own for too long.
