What is the name of Grignard Reagent that will give 2,2-Dimethyl Propanoic Acid on reaction with CO2?
Correct answer: D. Neo-Butyl Magnesium Bromide
- A. n-Propyl Magnesium Bromide
- B. Iso-propyl magnesium Bromide
- C. N-Butyl Magnesium Bromide
- D. Neo-Butyl Magnesium Bromide
Explanation
Neopentylmagnesium bromide, often referred to as neo-butyl magnesium bromide, is a Grignard reagent derived from neopentyl bromide. On recation with CO2, it will yield 2,2-dimethyl propanoic acid.

About Nomenclature, Structure and Preparation
Carboxylic acids are prepared by oxidising primary alcohols or aldehydes, hydrolysing nitriles, esters and amides, and carbonating suitable organometallic compounds. Their structures, IUPAC naming, resonance stabilisation and acidic character explain why carboxylic acids differ from alcohols and phenols, despite all containing oxygen and hydrogen.
