Hunsdiecker reaction is first notated by _ _ _ _ _ _ in 1961.A.BorodinB.HunsdieckerC.ClareD. None of these

The Hunsdiecker reaction, which is an important reaction in organic chemistry, was first reported by Hunsdiecker in 1961. This reaction involves the conversion of silver salts of carboxylic acids to the corresponding alkenes by treatment with halogens, typically bromine or chlorine.

So, the correct answer to the question is:

B. Hunsdiecker

Explanation:
Hunsdiecker Reaction: It is named after the chemist who discovered it, Hunsdiecker, and involves a decarboxylation mechanism that is significant in organic synthesis for forming alkenes from carboxylic acid derivatives.
Historical Context: The reaction was significant in the context of synthetic organic chemistry as it provided a method for creating alkenes from carboxylic acids, which can be further utilized in various chemical processes.
