Final answer:
The molecule C₂F₂ consists of one triple bond between the two carbon atoms and two single bonds between each carbon and fluorine atom, totaling five covalent bonds.
Step-by-step explanation:
The molecule C₂F₂, known as difluoroacetylene, consists of two carbon atoms and two fluorine atoms. According to valence bond theory, carbon typically forms four bonds to achieve an octet, due to having four valence electrons. In this molecule, each carbon atom forms a triple bond with the other carbon and a single bond with a fluorine atom.
Therefore, in C₂F₂, we find one triple bond (which is made up of one sigma bond and two pi bonds) between the two carbon atoms and two single bonds, one between each carbon and fluorine atom, for a total of five covalent bonds.
