A. A species with an unpaired electron
B. A positively charged ion
C. A molecule with a complete octet

A species with an unpaired electron

Explanation

A free radical is characterized by having an unpaired electron, making it highly reactive. This property is important in various organic reactions, particularly in chain reactions.

Common mistake

Confusing Nucleophiles and Electrophiles

Students often confuse nucleophiles with electrophiles, thinking both are electron donors.

Remember that nucleophiles are electron-rich species that donate electrons, while electrophiles are electron-deficient species that accept electrons. A nucleophile can be defined as a species that has a lone pair of electrons or a negative charge, whereas an electrophile is typically positively charged or has a partial positive charge.
