Is alkanes an organic compound?
Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups.
What type of compound is alkene?
Alkenes are a class of hydrocarbons (e.g, containing only carbon and hydrogen) unsaturated compounds with at least one carbon-to-carbon double bond. Another term used to describe alkenes is olefins. Alkenes are more reactive than alkanes due to the presence of the double bond.
What is a alkene in organic chemistry?
Alkenes are acyclic (branched or unbranched) hydrocarbons having one carbon-to-carbon double bond (C=C) and the general molecular formula CnH2n [16]. Because alkenes contain less than the maximum possible number of hydrogen atoms per carbon atom, they are said to be unsaturated.
What is the alkene group?
The simplest are the alkenes, which are hydrocarbons which have carbon-carbon double bond functional groups and are unsaturated hydrocarbons with the molecular formula is CnH2n, which is also the same molecular formula as cycloalkanes. The root chain must be numbered from the end nearest a double bond carbon atom.
Are alkenes soluble?
Alkenes are non-polar, and they are both immiscible in water and less dense than water. They are generally soluble in organic solvents.
Is alkene a functional group?
The functional group in an alkene is a carbon-carbon double bond. The functional group in an alkyne is a carbon-carbon triple bond. Aromatics are cyclic strcutures that are planar, fully conjugated and that possess an odd number of electron pairs in the π bonding system….FG1. Hydrocarbons.

Are all alkenes hydrocarbons?
The alkenes are unsaturated hydrocarbons: hydrocarbons , because they are compounds containing hydrogen and carbon only. unsaturated, because they contain a C=C double bond, which means that they have two fewer hydrogen atoms than the corresponding alkane.
Do alkenes Decolourise bromine?
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.
Are alkenes inorganic?
Alkenes are generally colorless apolar compounds, somewhat similar to alkanes but more reactive. The first few members of the series are gases or liquids at room temperature. The simplest alkene, ethylene (C2H4) (or “ethene” in the IUPAC nomenclature) is the organic compound produced on the largest scale industrially.
How do you name organic compounds alkenes?
Alkenes and alkynes are named by identifying the longest chain that contains the double or triple bond. The chain is numbered to minimize the numbers assigned to the double or triple bond. The suffix of the compound is “-ene” for an alkene or “-yne” for an alkyne.
Are alkenes functional group?
They include alkanes, alkenes, alkynes and aromatics. The latter three are considered different types of functional groups. Alkanes are not usually considered as functional groups; instead, an alkane is a compound that lacks functional groups. The functional group in an alkene is a carbon-carbon double bond.
Why are alkenes insoluble?
Density. Alkenes are lighter than water and are insoluble in water due to their non-polar characteristics. Alkenes are only soluble in nonpolar solvents.
What is the chemical formula for alkenes?
General Molecular Formula of Alkenes Alkenes have the general chemical formula C n H 2n. Alkanes are said to be unsaturated hydrocarbons because they do not contain the maximum number of Hydrogen atoms that a molecule can possess. Molecular Structure of Alkenes
Are alkynes more electrophilic than alkenes?
Alkynes are less reactive than alkenes towards electrophilic addition reaction. Why? There are two reasons for less reactivity of Alkynes towards electrophillic addition reactions:-. Due to greater electronegativity of sp-hybridized carbon atoms of a triple bond than sp2 -hybridized carbon atoms of a double bond, pie-electrons of alkynes are more tightly held by the carbon atoms than pie electrons of alkenes and hence are less easily available for reaction with electrophiles.
What are some common examples of alkynes in chemistry?
In systematic chemical nomenclature, alkynes are named with the Greek prefix system without any additional letters. Examples include ethyne or octyne. In parent chains with four or more carbons, it is necessary to say where the triple bond is located.
What is an example of an alkane?
Alkanes are saturated hydrocarbon consist of carbon and hydrogen only without any functional group. The general formula of alkane is C nH 2n+2. Example: methane (CH 4), ethane (C 2H 6), propane (C 3H 8) etc.
