In organic chemistry, a cycloalkene or cycloolefin is a type of alkene hydrocarbon which contains a closed ring of carbon atoms and either one or more double bonds, but has no aromatic character. Some cycloalkenes, such as cyclobutene and cyclopentene, can be used as monomers to produce polymer chains. [1]

Bridged cycloalkanes

WebAug 13, 2024 · If the two rings are bridged at two or more carbon atoms, the carbon atoms form part of a bridge, and the compound is a bicycloalkane (for two rings) or a polycycloalkane (for three or more rings). An aromatic bicyclic compound is naphthalene (C 10 H 8 ), which is a pair of benzene rings fused across a carbon-carbon bond. WebNov 13, 2024 · In this work, a novel ring-bridged polymer lubricant (PIBOA) was prepared from monomers of isobornyl acrylate (IBOA) and its tribological performance was evaluated, which indicates that the functional group of bridged cycloalkanes can control the coefficient of friction compared with the polymethyl methacrylate (PMMA) lacking the “hook” group.

In cycloalkanes, the carbon atoms are sp hybridized, which would imply an ideal tetrahedral bond angle of 109° 28′ whenever possible. Owing to evident geometrical reasons, rings with 3, 4, and (to a small extent) also 5 atoms can only afford narrower angles; the consequent deviation from the ideal tetrahedral bond angles causes an increase in potential energy and an overall destabilizing effect. Eclipsing of hydrogen atoms is an important destabilizing effect, as well. The strain … WebSep 24, 2024 · These compounds are known as cycloalkanes.
