Which of the following cannot be written in an isomeric form? a) CH3-C...
Answer:

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.

Similar Class 12 Doubts

Poetry is an art form that has survived for thousands and thousands of years. We study it in school, and we hear quotes from poems scattered throughout our life.But do we ever truly make meaning of it? Does it even matter? My answer to you is yes it does. Reading poetry and or writing poetry can drastically improve your life.Poetry is one of the most powerful forms of writing because it takes the English language, a language we believe we know, and transforms it. The pattern of the sentences sounds new and melodious. It is truly another language exclusively for the writer and the reader. No poem can be read in the same way, because the words mean something different to each of us. For this reason, many find poetry an elusive art form. However, the issue in understanding poetry lies in how you read poetry.Anyone who writes poetry can attest, you have to write it with an open heart. So, as a reader, we must do the same. Opening your heart to poetry is the only way to get fulfillment from it.From a writers perspective, writing poetry can be equally elusive as reading poetry. When I first started writing poetry, the advice I always heard was practice, find your voice, keep a journal. I did all these things but still my poems were flat and inert. What was I missing? I poured over poems by Angelou, Shakespeare, Austen, and Wilde looking for a pattern, something I could emulate. This was the problem. I was unwilling to open my heart. I thought poetry could be a mask I could craft. But no matter how beautiful I made it; it would never come to life. It would never fit on another persons face. It did not ever fit on mine.My first poem that came alive was written in the dark late at night. Vulnerability was the key. Poetry is about expressing those thoughts and feelings we keep the most suppressed. We must be honest with ourselves about what we feel in order to write anything worth reading. Its stopping and grabbing a thought by the tail and pulling it up into our conscious mind. Its trying to express the beauty, and wonder we see. Its about connecting our hearts and our minds to ourselves and our surroundings.Its about finding peace.So, reach for the pen, and let go of those things that have been burdening your freedom. Read poetry with your heart and let it affect you. The answer to our questions about the meaning of life, and the purpose of pain were written in poems. They have always been there.Q. Which of the following correctly mentions the demerit of emulating others in writing poetry?
