What are naphthenes in chemistry?
Naphthenes, also known as cycloalkanes, are saturated hydrocarbons that have at least one ring of carbon atoms. They have the general formula CnH2n. A common example is cyclohexane (C6H12). The boiling point and densities of naphthenes are higher than those of alkanes having the same number of carbon atoms.
What are paraffins naphthenes and aromatics?
Paraffins – straight chain of saturated hydrocarbons. Isoparaffins – branched chain of saturated hydrocarbons. Aromatics – unsaturated hydrocarbons containing one or more benzene rings. Naphthenes – cyclic chain of saturated hydrocarbons.
What is the use of naphthenes?
Naphthenes are an important component of liquid petroleum refinery products. Most of the heavier boiling point complex residues are cycloalkanes. Naphthenic crude oil is more readily converted into gasoline than paraffin-rich crudes are.
What is the main difference between aromatics and naphthenes?
The key difference between naphthenes and aromatics is that the naphthenes have only single bonds between carbon atoms whereas the aromatics have both single bonds and double bonds between carbon atoms. We call naphthenes “cycloalkanes”. These are cyclic aliphatic hydrocarbon compounds.
Which of the following is Naphthenes?
Cycloalkanes are called naphthenes.
What are paraffins give two examples?
Paraffins are straight- or branched-chain hydrocarbons having the chemical formula CnH2n+2. The name of each member ends with –ane; examples are propane, isopentane, and normal heptane (Figure 3.1). Figure 3.1.
Is isobutane a paraffin?
The second group of paraffins is called isoparaffins, which are branched-type hydrocarbons, and they begin with isobutane (also called methylpropane), which has the same closed formula as n-butane (C4H10). Compounds of different structures with the same closed formula are called isomers (Figure 1.9).
Which hydrocarbon is known as olefins?
alkene
olefin, also called alkene, compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond. Olefins are examples of unsaturated hydrocarbons (compounds that contain only hydrogen and carbon and at least one double or triple bond).
What is general formula of Naphthenes?
Naphthenes is also called Cycloalkanes or Cycloparaffins. Their General formula is CnH2n+n-2N where n is the no. of carbon atom and N is the naphthenic ring.
What do you mean paraffin?
Definition of paraffin 1a : a waxy crystalline flammable substance obtained especially from distillates of wood, coal, petroleum, or shale oil that is a complex mixture of hydrocarbons and is used chiefly in coating and sealing, in candles, in rubber compounding, and in pharmaceuticals and cosmetics.

What is meaning of isobutane?
Definition of isobutane : a gaseous branched-chain hydrocarbon (CH3)3CH isomeric with normal butane that is used especially as a fuel.
What are naphthenes give an example?
Naphthenes Definition and Examples. Naphthenes are a class of cyclic aliphatic hydrocarbons obtained from petroleum. Naphthenes have the general formula C n H 2n. These compounds are characterized by having one or more rings of saturated carbon atoms. Naphthenes are an important component of liquid petroleum refinery products.
What is the chemical formula for naphthenes?
Naphthenes are a class of cyclic aliphatic hydrocarbons or simply Cycloalkanes. The general form of the chemical formula for cycloalkanes is CnH2(n+1−r), where n is the number of carbon atoms and r is the number of rings.They are similar to alkanes in their general physical properties, but they have higher boiling points,…
Are naphthalene and naphthenes the same thing?
Note naphthenes are not the same as the chemical called naphthalene. Also Known As: Naphthenes are also known as cycloalkanes or cycloparaffin.
What are cycloalkanes or naphthenes?
The cycloalkanes or naphthenes are a special class of alkanes with ring structure. Naphthenic hydrocarbons have the formula Cn H 2n and all C―H bonds are saturated. As such, naphthenic hydrocarbons in petroleum are also relatively stable compounds.
