Question

which of the following chemical substances has a triple covalent bond?
water (h₂o)
carbon monoxide (co)
carbon dioxide (co₂)
oxygen (o₂)

Explanation:

• Oxygen (\(O_2\)): It has a double covalent bond (\(O = O\)).
• Carbon dioxide (\(CO_2\)): It has two double covalent bonds (\(O = C = O\)).
• Carbon monoxide (\(CO\)): It has a triple covalent bond (\(C\equiv O\)).
• Water (\(H_2O\)): It has two single covalent bonds (\(H - O - H\)).

Answer:

Carbon monoxide (CO)
