Question

part a
what is the difference between a common name for a compound and a systematic name?
the common name provides the reader with enough information that the formula of the compound can be determined. the systematic name is just like a nickname for the compound.
the systematic name provides the reader with enough information that the formula of the compound can be determined. the common name is just like a nickname for the compound.
there is no difference.

Explanation:

To determine the difference between a common name and a systematic name of a compound, we analyze the options:

• The first option incorrectly swaps the roles of common and systematic names.
• The second option is correct: Systematic names (like IUPAC names) provide structural/formula information, while common names are colloquial "nicknames" (e.g., acetic acid is systematic, vinegar acid - like common, but more accurately, common names are familiar terms, systematic are formal with structural info).
• The third option is wrong as there is a difference.

Answer:

The systematic name provides the reader with enough information that the formula of the compound can be determined. The common name is just like a nickname for the compound. (Assuming the middle option is the correct one based on the description, if the options were labeled, e.g., B. The systematic name provides... nickname for the compound.)
