What is a ring structure in chemistry?
In chemistry, a ring is an ambiguous term referring either to a simple cycle of atoms and bonds in a molecule or to a connected set of atoms and bonds in which every atom and bond is a member of a cycle (also called a ring system). A molecule containing no rings is called an acyclic or open-chain compound.
What molecule has a ring structure?
Aromatic rings (also known as aromatic compounds or arenes) are hydrocarbons which contain benzene, or some other related ring structure. Benzene, C6H6, is often drawn as a ring of six carbon atoms, with alternating double bonds and single bonds: This simple picture has some complications, however.

What is fused ring structure?
FR-1.2 Fused ring system. A system where each bond is part of a ring; where each ring is ortho-fused (FR-1.1. 1), or ortho- and peri-fused (FR-1.1. 2), to at least one other ring; and where no bond is common to more than two rings is termed a fused ring system.
How does the structure affect properties?
The properties of organic molecules depend on their structure being made of simple molecules . The intermolecular forces between molecules are weaker. The intermolecular forces vary between molecules, so different organic compounds have different melting points and boiling points.
How do we know the structure of molecules?
The methods by which one can elucidate the structure of a molecule include: concerning only connectivity of the atoms: spectroscopies such as nuclear magnetic resonance (proton and carbon-13 NMR), various methods of mass spectrometry (to give overall molecular mass, as well as fragment masses).
What is the general term used to describe an alkane in a ring structure?
Cycloalkanes are also called naphthenes. Branched-chain alkanes are called isoparaffins. “Paraffin” is a general term and often does not distinguish between pure compounds and mixtures of isomers, i.e., compounds of the same chemical formula, e.g., pentane and isopentane.
What are fused ring aromatic compounds?
[¦fyüzd ar·ə¦mad·ik ′riŋ] (organic chemistry) A molecular structure in which two or more aromatic rings have two carbon atoms in common.
What goes on a ring stand?
The ring stand has a heavy base and upright rod for supporting each accessory. A ring support attaches to the stand to support other equipment. Wire gauze rests on the ring to support glassware above an alcohol burner. The triangle rests on the ring to support funnels, crucibles and evaporating dishes.
What is an aromatic ring structure?
Aromatic rings (also known as aromatic compounds or arenes) are hydrocarbons which contain benzene , or some other related ring structure. Benzene, C6H6, is often drawn as a ring of six carbon atoms, with alternating double bonds and single bonds: This simple picture has some complications, however.
What is a double ring structure?
Answer Wiki. DNA has a double helix structure of two anti-parallel, complementary strands having a phosphate-sugar backbone with nitrogenous bases stacked inside it. The nitrogenous bases can be classified as purines and pyrimidines. Adenine (A) and Guanine (G) are purines which have a double ring structure while Cytosine (C) and Thymine (T)…
How many rings do pyrimidines have on their structure?
Matching base pairs composed of one purine and one pyrimidine form hydrogen bonds. Purines have a double ring structure, and pyrimidines have a single ring structure. Adenine and thymine both have two sites where they form hydrogen bonds to each other, while guanine and cytosine have three sites.
What is the ring structure for galactose?
Ring Structure for Galactose. In the chair structure this results in a horizontal projection ( Haworth – an upwards projection). The Alpha position is defined as the -OH being on the opposite side of the ring as the C # 6. In the chair and Haworth structure this results in a downward projection.
