There are over 27 million chemical compounds known and majorly organic compounds. There are many industries such as the food industry, pharmaceutical industries, and the color dye industry in which organic compounds are used. As a result, organic compounds have become our basic need in today's daily life.
Studying these many organic compounds separately is next to impossible. Thus there is a need for the classification of organic compounds. Organic substances can be categorized in two ways structurally and chemically i.e.,
Table of content:
A general classification of the organic compounds on the basis of structure is given below:
Example of straight-chain Acyclic compound:
Example of branched-chain Acyclic compound:
These are the compounds in which the carbon atoms are linked to each other or to the atoms of other elements in such a manner that the molecule has a closed-chain or cyclic or ring structure.
Alicyclic compounds are further classified into homocyclic and heterocyclic compounds:
Aromatic compounds are further classified into benzenoid, non-benzenoid, and heterocyclic aromatic compounds.
Example: Naphthalene, toluene, etc.
Q1: Cyclopentane is an example of which type of organic molecule?
C) Aromatic Heterocyclic
Answer : (A)
An alicyclic compound is an organic compound that is both aliphatic and cyclic.
Cyclopentane is a five-membered ring constituting only carbon atoms hence it is homocyclic.
Q2: Pyridine is an example of which type of organic molecule?
Answer : (C)
Pyridine is an example of a six-membered aromatic heterocycle and has an electronic structure similar to benzene.
Q3: Which among the following is not an example of an Acyclic compound?
Solution:Cyclopropane is a three membered cyclic compound containing all carbon atoms.
Q4: Which among these is not associated with aliphatic compounds?
Solution:Aliphatic compounds generally do not contain aromatic character, hence they do not follow the huckel rule.
Q5: Which among the following is not an example of a Cyclic compound?
Solution:Benzene, furan and cyclopropane all are cyclic organic compounds, isobutane is a branched acyclic organic compound.
Q 1: Write some applications of organic compounds.
Answer: There are many industries such as the food industry, pharmaceutical industries, and the color dye industry in which organic compounds are used. As a result, organic compounds have become our basic need in today's daily life.
Q 2: Give some examples of organic compounds used in medicine.
Answer: Organic compounds, frequently split into big groups of tiny organic molecules (e.g., atorvastatin, fluticasone, clopidogrel) and "biologics" (infliximab, erythropoietin, insulin glargine), the latter more generally employed as protein pharmaceutical goods, are most commonly utilized as medicinal products.
Q 3: Explain some properties of Organic compounds.
Answer: Physical properties of organic compounds of interest usually provide quantitative and qualitative information. The melting point, boiling point, and refraction index are all examples of quantitative data. Odor, durability, solubility, and colour are examples of qualitative qualities.
Q 4: What is the major source of organic compounds?
Answer:The main source of organic compounds is fossil fuels (petroleum, coal, plants, animals etc). hey have a very strong odor. For example, Benzene, Aniline, Naphthalene and so on.
