Question

The number of isomers for the compound with molecular formula ${C_2}HDFCl$ is-

Answer 1

Before attempting this question, one should have prior knowledge about the concept of isomers which is a compound with same numbers of atoms but different structure, use this information to approach the solution.

Complete answer:
Before approaching the solution let’s talk about what are isomers so the moles or polyatomic ions which have similar molecular formulas (number of atoms in each element is same) but different arrangement of atoms in a space this concept is named as isomers
According to the given information we have compound ${C_2}HDFCl$ which have total 3 numbers of isomers which are as follows-



The above diagram is the isomers structure of ${C_2}HDFCl$
Therefore, there are a total 3 numbers of isomers of compound ${C_2}HDFCl$.

Note:
In the above solution we discussed about the isomers but when it comes to structural isomers there comes three types of them which are chain isomers, functional group isomers and positional isomers where chain isomers have different arrangements of branches, functional isomers have different functional group and positional isomers different location of functional group or carbon chain.
