Cycloalkanes Saturated hydrocarbons that

The saturated hydrocarbons, or alkanes, are compounds in which each carbon atom is bonded to four other atoms. Cycloalkanes are saturated hydrocarbons that contain carbon atoms joined to form a ring. 

Cycloalkane A saturated hydrocarbon that contains carbon atoms joined to form a ring. 

Cycloalkanes are saturated hydrocarbons that have at least one ring of carbon atoms. A common example is cyclohexane. 

The alkanes are acyclic, saturated hydrocarbons that form a homologous series of compounds, with the general formula C H2 +2, The cycloalkanes are cyclic, saturated hydrocarbons that form another homologous series with the general formula C H2 in which the carbon atoms are joined in a ring. The...

Hydrocarbons fall into two broad classes based on the types of bonds between the carbon atoms. A hydrocarbon that has only carbon-carbon single bonds is saturated. Hydrocarbons that contain carbon-carbon multiple bonds are unsaturated. Alkanes and cycloalkanes are two types of saturated hydrocarbons. Alkanes have carbon atoms bonded in chains cycloalkanes have carbon atoms bonded to form a ring. 

We JI look in the next chapter at cycloalkanes—saturated cyclic hydrocarbons— and we ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why ... 

Cycloalkanes, like alkanes, are saturated hydrocarbons containing only single bonds. Notice, though, that as a result of ring formation, each cycloalkane molecule contains two fewer hydrogen atoms than the corresponding alkane. 

One of the most ubiquitous multiple-component contaminants that reaches the soil and deeper subsurface layers is crude oil and its refined products. In the subsurface, these contaminants are transformed differently by various mechanisms (Cozzarelli and Baber 2003). Crude oil contains a multitude of chemical components, each with different physical and chemical properties. As discussed in Chapter 4, the main groups of compounds in crude oils are saturated hydrocarbons (such as normal and branched alkanes and cycloalkanes without double bonds), aromatic hydrocarbons, resins, and asphaltenes, which are high-molecular-weight polycyclic compounds containing nitrogen, sulfur, and oxygen. 

The main groups of compounds in crude oils are saturated hydrocarbons (such as normal and branched alkanes and cycloalkanes that contain no double bonds), aromatic hydrocarbons, resins and asphaltenes (higher molecular weight polycyclic compounds containing nitrogen, sulfur. 

The cyclic saturated hydrocarbons, or cychalkanes, have the general formula C 2n-cycloalkanes (and other ring compounds that we will encounter later) are often shown in simplified skeletal form in which each intersection of two lines represents a C atom we mentally add enough H atoms to give each carbon atom four bonds. The first four unsubstituted cycloalkanes and their simplified representations are... 

The terminology saturated hydrocarbons used to describe alkanes and cycloalkanes conveys that these compounds are generally unreactive. They are the least reactive of all organic compounds. Unlike other families, alkanes and cycloalkanes do not contain a bond or bonds which are relatively... 

The idea that carbon atoms can be bound in cyclic structures (besides forming chains and branched chains) appeared during the second half of nineteenth century. When these cyclic structures are saturated hydrocarbons we talk about cycloalkanes. In the nomenclature of this class of compounds the name is formed by adding the prefix cyclo-. 

A hydrocarbon that contains carbon atoms joined to form a ring is called a cyclic hydrocarbon. When all carbons of the ring are saturated, we call the hydrocarbon a cycloalkane. Cycloalkanes of ring sizes ranging from 3 to over 30 abound in nature, and, in principle, there is no limit to ring size. Five-membered (cyclopentane) and six-membered (cyclohexane) rings are especially abundant in nature and have received special attention.
