Answer:
In organic chemistry, isomerism refers to the phenomenon where two or more compounds have the same molecular formula but differ in their structural arrangement or connectivity of atoms. Isomers can be categorized into different types such as structural isomers, stereoisomers, and functional isomers, depending on the nature of the differences.
To determine which of the given compounds cannot be written in an isomeric form, we need to analyze their structures and identify if they possess any structural or functional features that can be rearranged to form isomers.
This compound is a chain of four carbon atoms with a hydroxyl group (-OH) attached to the second carbon atom. It is an example of a primary alcohol. Since the hydroxyl group is attached to the second carbon atom, it cannot be rearranged to form any isomers. Therefore, compound a) cannot be written in an isomeric form.
This compound is an aldehyde, with a carbonyl group (-CHO) attached to a methyl group. Aldehydes can exhibit structural isomerism, known as functional group isomerism, where the position of the carbonyl group can change within the molecule. However, in this case, the carbonyl group is attached to the first carbon atom, which does not allow any isomer formation. Therefore, compound b) cannot be written in an isomeric form.
This compound is an example of a vinyl chloride, with a chlorine atom attached to the second carbon of a double bond. Vinyl chloride does not possess any structural features that can be rearranged to form isomers. Therefore, compound c) cannot be written in an isomeric form.
This compound is a symmetrical molecule known as 1,2-dichloroethane. It consists of two chlorine atoms attached to adjacent carbon atoms. Since the molecule is symmetrical, there is no possibility for any structural isomerism. Therefore, compound d) cannot be written in an isomeric form.
Among the given compounds, a), b), c), and d), only compound b) (CH3-CHO) can exhibit isomerism due to functional group isomerism. The remaining compounds do not possess any structural or functional features that allow them to exist in isomeric forms.
Introduction
In organic chemistry, isomerism refers to the phenomenon where two or more compounds have the same molecular formula but differ in their structural arrangement or connectivity of atoms. Isomers can be categorized into different types such as structural isomers, stereoisomers, and functional isomers, depending on the nature of the differences.
Explanation
To determine which of the given compounds cannot be written in an isomeric form, we need to analyze their structures and identify if they possess any structural or functional features that can be rearranged to form isomers.
a) CH3-CH(OH)-CH2-CH3
This compound is a chain of four carbon atoms with a hydroxyl group (-OH) attached to the second carbon atom. It is an example of a primary alcohol. Since the hydroxyl group is attached to the second carbon atom, it cannot be rearranged to form any isomers. Therefore, compound a) cannot be written in an isomeric form.
b) CH3-CHO
This compound is an aldehyde, with a carbonyl group (-CHO) attached to a methyl group. Aldehydes can exhibit structural isomerism, known as functional group isomerism, where the position of the carbonyl group can change within the molecule. However, in this case, the carbonyl group is attached to the first carbon atom, which does not allow any isomer formation. Therefore, compound b) cannot be written in an isomeric form.
c) CH2=CH-Cl
This compound is an example of a vinyl chloride, with a chlorine atom attached to the second carbon of a double bond. Vinyl chloride does not possess any structural features that can be rearranged to form isomers. Therefore, compound c) cannot be written in an isomeric form.
d) Cl-CH2CH2-Cl
This compound is a symmetrical molecule known as 1,2-dichloroethane. It consists of two chlorine atoms attached to adjacent carbon atoms. Since the molecule is symmetrical, there is no possibility for any structural isomerism. Therefore, compound d) cannot be written in an isomeric form.
Conclusion
Among the given compounds, a), b), c), and d), only compound b) (CH3-CHO) can exhibit isomerism due to functional group isomerism. The remaining compounds do not possess any structural or functional features that allow them to exist in isomeric forms.
