What are the 5 physical properties of alkanes?
Physical Properties of Alkanes
- Boiling Points.
- Solubility. Solubility in Water. Solubility in organic solvents.
What is alkane give the characteristics of alkanes?
Alkanes are the simplest family of hydrocarbons – compounds containing carbon and hydrogen only with only carbon-hydrogen bonds and carbon-carbon single bonds. Alkanes are not very reactive and have little biological activity; all alkanes are colorless and odorless.
What are the characteristics of alkene?
Alkenes are unsaturated carbon compounds which have a general formula of CnH2n. These compounds are also known as olefins. Alkenes are a family of compounds containing hydrogen and carbon only (hydrocarbons) with a carbon-carbon double bond. Ethene and Propene are the first two hydrocarbons.
What are the properties and uses of alkane?
Chemical Properties of Alkanes: Alkanes are relatively unreactive. Alkanes do not react with strong acids, bases, oxidising agents (oxidants) or reducing agents (reductants). Alkanes combust (react rapidly with oxygen) releasing energy, which makes alkanes useful as fuels.
What are the significant characteristics of alkenes and alkanes?
While alkanes and alkenes are both hydrocarbons, the primary difference is that alkanes are saturated molecules, containing only single covalent bonds (σ-bonds) between the carbon atoms whereas alkenes are unsaturated molecules containing a double covalent bond (combination of a π-bond and a σ-bond).
What are the classification of alkanes?
There are three types of alkanes: linear straight chain alkanes, branched alkanes, and cyclic alkanes.
What is the function of alkane?
Alkanes are important raw materials of the chemical industry and the principal constituent of gasoline and lubricating oils. Natural gas mainly contains methane and ethane and is used for heating and cooking purposes and for power utilities (gas turbines).
What are alkanes explain?
Alkanes are a series of compounds that contain carbon and hydrogen atoms with single covalent bonds. These are known as saturated hydrocarbons. This group of compounds consists of carbon and hydrogen atoms with single covalent bonds. Also comprises a homologous series having a molecular formula of CnH2n+2.
What are the structure of alkanes?
The alkanes comprise a series of compounds that are composed of carbon and hydrogen atoms with single covalent bonds. This group of compounds comprises a homologous series with a general molecular formula of C n H 2 n+2 , where equals any integer. Alkyl groups.
What is alkane with example?
Alkanes are saturated hydrocarbons. By saturated hydrocarbons, it means alkanes have single hydrogen and carbon atoms in their chemical formula. Formula of alkane is CnH2n+2. Methane, propane, ethane, and butane are four alkanes.
What are the characteristics of homologous series?
Characteristics are :
- The members of the homologous series have same functional group.
- Members have the same general formula.
- Members have the almost same chemical properties due to same functional group.
- Members have common general method of preparation.
What are the first 10 alkanes?

How are alkanes named?
Alkanes with unbranched carbon chains are simply named by the number of carbons in the chain. The first four members of the series (in terms of number of carbon atoms) are named as follows: CH4 = methane = one hydrogen-saturated carbon. C2H6 = ethane = two hydrogen-saturated carbons.
Why do alkanes form a homologous series?
The alkanes are a homologous series of hydrocarbons . This means that they have similar chemical properties to each other and they have trends in physical properties. For example, as the chain length increases, their boiling point increases.
What is the main character of isomers?
Characteristics of isomers: (i)They have the same molecular formula. (ii)They have different structural formulae. (iii)They have different melting and boiling points.
What is homologous series state any 4 characteristics?
Characteristics of a homologous series: Each member of the series differs from the preceding one by the addition of a -CH2 group and by 14 a.m.u. All members of a homologous series share the general formula. Example: The general formula for alkane is CnH2n+2 and alkene is CnH2n.
Which type of bond is found in an alkane?
single covalent bonds
Alkanes. Alkanes, or saturated hydrocarbons, contain only single covalent bonds between carbon atoms.
Is alkane a functional group?
Is alkane a functional group? Usually, alkanes are not considered functional groups; rather, an alkane is a compound that lacks functional groups. A carbon-carbon double bond is a functional group in an alkene.
Are alkanes saturated or unsaturated?
The alkenes are unsaturated. This means that they have a carbon to carbon double bond. The alkanes are saturated because they only contain single bonds.
Are alkanes polar or nonpolar?
Alkanes are nonpolar molecules, since they contain only nonpolar carbon-carbon and carbon-hydrogen bonds. They are therefore not soluble in water, and since they are generally less dense than water, they will float on water (e.g., oil slicks).
Are alkanes soluble in water?
Alkanes are not soluble in water, a polar substance. The two substances do not meet the usual criterion of solubility: “Like dissolves like.” Water molecules are too strongly attracted to each other by hydrogen bonds to allow nonpolar alkanes to slip in between them and dissolve.
What elements are present in alkanes?
We begin our study of organic chemistry with the alkanes, compounds containing only two elements, carbon and hydrogen, and having only single bonds.
How alkanes are formed?
Alkane can be prepared from alkene and alkyne through the process of hydrogenation. In this process, dihydrogen gas is added to alkynes and alkenes in the presence of a catalyst. These catalysts are finely divided and may include nickel, palladium or platinum to form alkanes.
