Question

which group is more powerful than -------CH3 group ?
a- -COOH
b- -OH
c- -CHO
d- -CN

Answer 1

Answer:

a) - COOH is the answer

Answer 2

The functional group more powerful than CH₃ is -COOH, -OH, -CHO,-CN.

• The priority of functional group follows the order:
• -COOH (carboxylic acids)
• -SO₃H (sulfonic acid)
• -CHO (aldehydes)
• -CN (cyanide)
• -CH₃(alkyl group)
• Among all the options -CH₃(alkyl group) has the least priority and the functional group -COOH (carboxylic acids) is at the top of the list.

• Hence, the groups above -CH₃ are more powerful.
• Options (a),(b),(c),(d) all are correct for the given question.
