What are the four characteristics of 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. … The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two.

According to vital force theory, organic compounds must have their origin in living organisms and consequently could never be synthesized from inorganic material. This theory is known as vital force theory.

Q. Who formulated vital force theory?


Q. 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.

Q. Are alkanes a homologous family?

Four characteristics of a homologous series are: (i) The general formula of all compounds in the series is the same. (ii) They have the same functional group. (iii) Their physical properties such as melting point, boiling point, density, generally show a gradual change with increase of molecular formula in the series.

Q. Which one is not a member of homologous series?


Q. What is homologous series Class 10?

Homologous Series. Homologous Series. 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.

Q. Do homologous series have same physical properties?

In a homologous series. they show a gradual variation in physical properties, such as their boiling points. they have similar chemical properties.

Q. Which of the following are members of same homologous series?

CH3OH,C2H5OH,C3H7OH are the member of the same homologous series as they all contain same basic structure and the difference in each case is -CH2- group.

Q. Is the functional group?

Functional groups are specific groupings of atoms within molecules that have their own characteristic properties, regardless of the other atoms present in a molecule. Common examples are alcohols, amines, carboxylic acids, ketones, and ethers.

Q. Which homologous series contains ethane?

The first homologous series is the alkanes. Their names all end in –ane. The alkanes have many uses: methane – (natural gas) cooking, heating….Alkanes.

Methane CH 4 Monsters
Ethane C 2H 6 Eat
Propane C 3H 8 Pupils
Butane C 4H 10 But
Pentane C 5H 12 Prefer

Q. Why do members of a homologous series have similar chemical properties?

The chemical properties of homologous series are similar because they have the same functional group. However, the physical properties of homologues are different because of increased London dispersion forces. Other molecules besides organic compounds can have homologous series as well.

Q. 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.

Q. What is the difference between two consecutive homologous chemical properties?

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.

Q. What is the next homologue of C3H7OH called?


Q. What is the difference between alkyl group and alkane?

Re: Alkane vs Alkyl An alkane is a saturated hydrocarbon, which means there are only carbon-carbon single bonds. The -ane part of the naming is what indicates that the hydrocarbon has only single bonds. Alkyls are the substituents in alkanes. When naming the substituent, the ending -ane is changed to -yl.

Q. What is meant by Catenation with an example?

Catenation Definition: Catenation is the binding of an element to itself through covalent bonds to form chain or ring molecules. Examples: Carbon is the most common element that exhibits catenation. It can form long hydrocarbon chains and rings like benzene.

Q. What is Catenation short answer?

Catenation : The self linkage is known as catenation. The property of catenation is responsible for the occurrence of innumerable oragnic compounds. It is the binding of an element to itself through covalent bonds to form chain or ring molecules. … That means it can form long hydrocarbon chains and rings like benzene.

Q. What are the three types of Catenation?

Examples of Catenation

  • Carbon.
  • Silicon.
  • Sulfur.
  • Boron.
