The first member of alkyne hom*ologous series is: (2024)

As an enthusiast and expert in chemistry, particularly in the realm of alkyne hom*ologous series, I bring a wealth of knowledge and expertise to shed light on the question at hand.

Firstly, let's establish the fundamentals. The alkyne series is characterized by triple bonds between carbon atoms. This is a crucial detail to grasp when identifying the first member of this hom*ologous series. The formula for alkynes is CnH2n-2, reflecting the presence of triple bonds.

Now, addressing the specific question, "The first member of alkyne hom*ologous series is:" — the correct answer is (a) ethyne. Ethyne is composed of two carbon atoms connected by a triple bond (HC≡CH). This molecule is also commonly known as acetylene.

To further solidify the evidence, it's essential to recall the structural formula of ethyne and understand its position within the alkyne hom*ologous series. The triple bond imparts unique chemical properties to ethyne, distinguishing it from other members of the alkane and alkene series.

In summary, the alkyne series is characterized by triple bonds, and the first member, ethyne, plays a pivotal role in understanding the subsequent members of this hom*ologous series. With this foundation, one can navigate related questions in chemistry effectively, as demonstrated by the additional questions provided:

Q1: The first member of the ester hom*ologous series is? Q3: Write the first five members of the hom*ologous series of aldehydes. Q4: Write the first five members of the hom*ologous series of alkenes. Q5: The first member of the hom*ologous series of ketones is.

These questions build upon the knowledge of hom*ologous series, which involves compounds with similar structures and properties, and understanding the systematic progression of these series based on molecular structure. Such knowledge is essential for a comprehensive understanding of organic chemistry.
