What is the difference between homologous series and functional group?
Functional group : is an atom or group of atoms in an organic molecule which characterised the molecule and enables it to react in specific ways (determines its chemical properties) .
A homologous series: a group of compounds with the same functional group.
• Members of the same homologous series: homologs..
What are the first 10 alkynes?
Here are the molecular formulas and names of the first ten carbon straight chain alkynes….Introduction.NameMolecular FormulaEthyneC2H2PropyneC3H41-ButyneC4H61-PentyneC5H85 more rows•Jun 5, 2019
What are 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 is the simplest alkyne?
The simplest alkyne—a hydrocarbon with carbon-to-carbon triple bond—has the molecular formula C2H2 and is known by its common name—acetylene (Figure 13.6. … Acetylene (ethyne) is the simplest member of the alkyne family. Acetylene is used in oxyacetylene torches for cutting and welding metals.
How do you find homologous series?
Such organic compounds that vary from one another by a repeating unit and have the same general formula form a series of compounds. Alkanes with general formula CnH2n+2, alkenes with general formula CnH2n and alkynes with general formula CnH2n-2 form the most basic homologous series in organic chemistry.
Is c3h4 an alkyne?
C3H4 is an alkyne because it has a triple bond in between its carbon atoms and follows the standard formula of alkynes that is CnH2n-2.
What are the homologous series of alcohol?
The alcohols are a homologous series of organic compounds . They all contain the functional group –OH, which is responsible for the properties of alcohols. The names of alcohols end with ‘ol’, eg ethanol. The first three alcohols in the homologous series are methanol, ethanol and propanol.
Which is not a first member of given homologous series?
All are alkenes except 2-butyne. So, 2-butyne does not form the member of homologous series.
What is the difference between two members of homologous series?
In term of molecular mass each successive member in a homologous series differ by molecular mass of 14 Dalton by the preceding member. … There is a difference of one carbon atom and two hydrogen atom between two consecutive members of homologous series that is of one CH2 molecule or three atoms.
What is the meaning of homologous?
1a : having the same relative position, value, or structure: such as. (1) biology : exhibiting biological homology. (2) biology : having the same or allelic genes with genetic loci usually arranged in the same order homologous chromosomes.
Which of the following belong to homologous series of alkynes?
Answer – C3H4 belongs to homologous series of alkyne. Homologous series is the series comprising of compounds that share same chemical properties and functional groups. Alkynes have formula C(2)H(2n-2). C6H6 or henzene is an aromatic compound.
What is the homologous series of alkene?
The general formula for the homologous series of alkenes is CnH2n where n is the number of carbon atoms. Because alkenes are hydrocarbons with at least one carbon-carbon double bond the alkene homologous series starts at ethene C2H4.
What is homologous series and its properties?
> A homologous series is a series of hydrocarbons which have similar chemical properties and they share the same general formula. They are organic compounds having similar structure and functional groups. The constituents of the homologous series shoe a gradation in physical properties.
What is homologous series class 10th?
A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. These compounds have similar chemical properties due to the addition of same kind of functional group throughout the chain.
What is the importance of homologous series?
1. Homologous series is the characteristic feature of carbon compounds in which carbon and hydrogen atoms in hydrocarbons varying by single parameter. 2. Homologous series helps in determination of structure of the successive member of the series and the property of that members can also be predicted by their series.
What is the name and formula of 2nd member of homologous series of alcohol?

What is a functional group Class 10?
An atom or a group of atoms present in the molecules, which determines the characteristics property of the organic compounds, is called the functional group. Organic compound. Functional group.
What is homologous series in simple words?
From Wikipedia, the free encyclopedia. In organic chemistry, a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or differ by -CH2.
What is the first alkyne?
Alkynes are organic molecules made of the functional group carbon-carbon triple bonds, with the general formula;CnH2n−2. They are unsaturated hydrocarbons. The first member of alkyne family is CH≡CH; Ethyne.
Are alkanes a homologous family?
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. The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two. …
