Question

state of hydrocarbon on the basis of carbon atom present in that hydrocarbon

Answer 1

Hydrocarbon, any of a class of organic chemical compoundscomposed only of the elementscarbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations. Hydrocarbons are the principal constituents of petroleumand natural gas. They serve as fuels and lubricants as well as raw materials for the production ofplastics, fibres, rubbers, solvents,explosives, and industrial chemicalsAliphatic Hydrocarbons

Aliphatic hydrocarbons are compounds of hydrogen and carbon that do not contain benzene rings. We'll discuss compounds with benzene rings later in this lesson. Aliphatic hydrocarbons tend to be flammable. There are several types of aliphatic hydrocarbons: alkanes, alkenes, alkynes and alkenynes.

Let's start with alkanes and cycloalkanes.Alkanes are linear, or branching, compounds that are made of varying numbers of carbon atoms that are all saturated with hydrogen atoms. The formula for an alkane is CnH(2n+2). This means that the number of hydrogen atoms equals twice the number of carbon atoms, plus two.

Methane is the simplest hydrocarbon possible. It is released as a gas from decomposing bodies and from the intestinal tracts of many animals. Its formula is CH4. Amethyl group, with the formula CH3, has one free bond to join something else.

Building on methane, some other alkanes are ethane (C2H6), propane (C3H8), butane (C4H10) and pentane (C5H12). Each adds one carbon to the chain. Note in the diagram that each carbon is saturated.

Various alkanes. Note that all carbons are saturated and that there are no double or triple bonds.

Cycloalkanes are a type of alkane that contain a carbon ring but not a benzene ring. These molecules still have only single bonds and thus, are saturated. Cycloalkanes are generally similar to their alkane, like cyclopropane or cyclobutane, but may have higher boiling and melting points.
