Q1. Ethyl magnesium bromide is bubbled with dry ice (solid CO2) followed by treatment with dilute HCl. Which organic acid is synthesized in this reaction?
Answer: Propanoic acid
Explanation: Grignard reagents add to CO2 to form a salt that hydrolyzes to a carboxylic acid. Ethanol is tempting but requires an aldehyde.
