Name the reagent and explain the process of 1-bromoethane into propanoic acid

Produce the Grignard reagentMg in a dry ether (ethoxyethane) with CH3CH2BrCH3CH2Br + Mg ---> CH3CH2MgBrAddition reaction with the Grignard and CO2 to produce a Carboxylic acid Must be hydrolysed using a dilute acid H2OCh3CH2MgBr + CO2 ---> CH3CH2COOH + Mg(OH)Br
