Respuesta :

Answer:

d. carboxyl

Explanation:

The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.

For example:

  • Formic acid or Methanoic acid (H-COOH)  
  • Butanoic acid (C3H7-COOH)

Hence, the correct option is "d. carboxyl ".
