What is a fused ring?
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.
What is fused benzene ring?
Benzene rings may be joined together (fused) to give larger polycyclic aromatic compounds. A few examples are drawn below, together with the approved numbering scheme for substituted derivatives. The peripheral carbon atoms (numbered in all but the last three examples) are all bonded to hydrogen atoms.
What are fused ring hydrocarbons?
Abstract. The term ring assembly denotes a polycyclic hydrocarbon in which two or more rings (or fused ring systems) are joined directly by single or double bonds and in which the number of such direct ring junctions is one less than the total number of rings and ring systems.
What can contain two or more fused rings?
Polycyclic aromatic hydrocarbons consist of two or more benzene rings fused together.
How do you name fused rings?
1 Hydrocarbons consisting of four or more ortho-fused benzene rings in a rectilinear arrangement are named by citing a numerical prefix denoting the number of benzene rings followed by the term ‘-acene’ with elision of an ‘a’ .
What is meant by fused compound?
fused compound is a type of chemical reaction in which base+phenolphthalein=hydrogen +salt .Such types of reaction is fused.
Which is fused cyclic aromatic Cycloalkane?
@ : Home > Chemistry > Aromatic Hydrocarbons. Which is fused cyclic aromatic compound. [A]. diphenyl amine.
How do you number a fused ring?
The system thus oriented is numbered in a clockwise direction commencing with the carbon atom not engaged in ring-fusion in the most counter-clockwise position of the uppermost ring, or if there is a choice, of the uppermost ring farthest to the right, and omitting atoms common to two or more rings.
What is fused heterocyclic ring?
2. • Fused heterocycles are systems constructed by. combining two or more rings. • The rings are fused if they are linked in such a way that. each ring has one common bond (fusion bond) to each.
What is a carbon ring called?
Carbocycles. The vast majority of cyclic compounds are organic, and of these, a significant and conceptually important portion are composed of rings made only of carbon atoms (i.e., they are carbocycles).
What is difference between fused and molten?
As adjectives the difference between molten and fused is that molten is melted while fused is joined together by fusing.
What is fused solution?
Fused salts are a large class of liquids that are composed largely of ions. Many simple inorganic salts melt at high temperatures (greater than 600°C or 1100°F), forming liquids which have high specific ionic conductivities (1–6 ohm−1 cm−1).
What is the difference between acyclic and alicyclic hydrocarbons?
Answer. Alicyclic hydrocarbons are those compounds which contain ring of 3 or more carbon atoms which resemble aliphatic (acyclic) hydrocarbons in their properties….question_answer Answers(3)

Which one of the following is not a fused ring system?
Diphenyl does not contain fused rings of benzene instead it contains two phenyl rings attached to each other.
What is fused in chemistry?
Fused: (1) Two or more rings that share an edge (i.e., the share two bonded atoms). Naphthalene is a fused bicyclic aromatic molecule. The shared atoms and bond that cause the molecule to be fused are shown in red.
What is a five carbon ring called?
The name cyclopentane indicates a cyclic (cyclo) alkane with five (pent-) carbon atoms. It can be represented as a pentagon. The name methylcyclobutane indicates a cyclic alkane with four (but-) carbon atoms in the cyclic part.
What does fused state mean?
Fused state is melting of the solid substance followed by its solidification. Solid state is the compact arrangement of the substance or element or compound. In the fused state metal conduct electricity. Its due to delocalisation of electrons.
What is fused state definition?
What is the meaning of fused?
To join (different pieces or elements) together physically, as by melting or heating: bits of glass fused in a kiln; atomic nuclei that are fused together inside the stars. b. To blend or combine together: “Edison’s invention strategy effectively fused research and development in a seamless process” (Seth Shulman).
What is an fused aromatic ring?

What is the origin of the word fuser?
