What type of compound contains the group that is circled?

To answer the question, we need to identify the compound that contains the circled group. However, since you haven't provided any specific information or context, it is difficult to determine the exact compound or group that is being referred to.

To proceed, we would need more details such as the molecular formula or structure of the compound, or any other relevant information that can help us identify the circled group. Once we have this information, we can analyze the compound and determine the type of compound and the group that is circled.
