Question

how is pentaoic acid prepared using grignard reagent​

Answer 1

Answer:

Grignard reagent reacts with solid CO2 (dry ice) to form magnesium salt of carboxylic acid. This is followed by acidification to obtain carboxylic acid. For example, the reaction between methyl magnesium bromide and carbon dioxide followed by acid hydrolysis will give acetic acid.

$<p style="color:pink;font-family:cursive;background:cyan;font size:25px;">The reaction of grignard reagents with crushed dry ice or solid carbon dioxide leads to the formation of salts of carboxylic acids. Further, the acidification of the salts of a carboxylic acid with mineral acids leads to the formation of corresponding carboxylic acids.$
