Question

When of the following is an alicyclic compound?
A)Cyclo pentanol
B)Cyclohexane
C)Benzene
D)Both A and B

Answer 1

Aliphatic organic compound is an organic compound in which the constituent atoms of the compound are connected with each other via bonds. Now, these bonds may either be single bonds, dual bonds or triple bonds. Aliphatic compounds are again further classified on the basis of the number of bonds present between two atoms of the compound. Compounds with single bond, double bond and triple bond are known as alkanes, alkenes and alkynes respectively.

Complete Step-by-Step Answer:
Before we move forward with the solution of the given reaction, let us understand some important basic concepts.
In organic chemistry, there are two main types of molecular structures that we can find. One is a chain - based structure, while the other is a cyclic based structure. Chain based structures are known as aliphatic organic compounds.
Alicyclic organic compounds are compounds in which there exist both a cyclic structure as well as a chain or an aliphatic structure. To put it in simpler terms, alicyclic compounds have two main parts in their molecules: the first part is a cyclic structure like benzene, while the second part is a chain structured organic compound.
To determine which of the given compounds are alicyclic, we must draw their corresponding molecular structures and then compare.
1.Cyclo pentanol

2.Cyclohexane

3.Benzene

From the above structures, we can observe that only cyclo pentanol clears all the criteria for being classified as an alicyclic compound.
Hence, Option A is the correct option

Note: Cyclo pentanol is used in medicine, dyes preparation and spices, it can also be used for solvent of drugs and spices. It is used for organic synthesis intermediates, it is used for pharmaceuticals, dyes and spices production
