Ethanoic acid undergoes Hell - Volhard Zelinsky reaction but Methanoic acid does not because of
Ethanoic acid undergoes Hell - Volhard Zelinsky reaction but Methanoic acid does not because of
- Absence of α-H atom in Ethanoic Acid
- Presence of α-H atom in Methanoic Acid
- Higher acidic strength of ethanoic acid than Methanoic Acid
- Presence of α-H atom in Ethanoic Acid
The Correct Option is D
Solution and Explanation
The Hell-Volhard-Zelinsky (HVZ) reaction is a method used for the α-bromination of carboxylic acids. In this reaction, the carboxylic acid is treated with phosphorus tribromide (PBr3) and a small amount of red phosphorus (P) as a catalyst. The resulting product is an α-bromo acid.
Methanoic acid (formic acid) does not undergo the Hell-Volhard-Zelinsky reaction, whereas ethanoic acid (acetic acid) does. The reason for this is due to the presence of an α-hydrogen atom in ethanoic acid.
Therefore, the correct answer is (D) Presence of α-H atom in Ethanoic Acid.

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
