In organic chemistry, the cycloalkanes (also called naphthenes, but distinct from naphthalene) are the monocyclic saturated hydrocarbons. [1] In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains ), and all of the carbon-carbon bonds are single .
Simple cycloalkanes have a prefix "cyclo-" to distinguish them from alkanes. Cycloalkanes are named as per their acyclic counterparts with respect to the number of carbon atoms in their backbones, e.g., cyclopentane (C 5 H 10 ) is a cycloalkane with 5 carbon atoms just like pentane (C 5 H 12 ), but they are joined up in a five-membered ring.
Cycloalkenes have a lower melting point than cycloalkanes of the same size. The lowered melting point is due to the double bond preventing the compound from compact packing. Cycloalkenes generally reflect physical properties of their cycloalkane. In physical states, only the smaller cycloalkenes are gases while the others are mostly liquid.
Cycloalkanes are hydrocarbons that form one or more rings. See also. Category:Cycloalkenes; Subcategories. This category has the following 6 subcategories, out of 6 ...
Cyclopropane is the cycloalkane with the molecular formula (CH 2) 3, consisting of three methylene groups (CH 2) linked to each other to form a triangular ring.The small size of the ring creates substantial ring strain in the structure.
Cyclohexane is a cycloalkane with the molecular formula C 6 H 12.Cyclohexane is non-polar.Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used).
Cyclohexene is an alicyclic compound with a double bond.. Monocyclic cycloalkenes are cyclopropene, cyclobutene, cyclopentene, cyclohexene, cycloheptene, cyclooctene, and so on.
A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
