Answer 1

• ozone o3

• In first structure the oxygen combined with second oxygen by double covalent bond and the oxygen combined with third oxygen by coordinate bond.
• In second structure the oxygen combined with second oxygen by coordinate bond and the oxygen combined with third oxygen by double covalent bond.
• Note : co-ordinate bond is a special type of covalent bond in which two atoms are held together by a shared electron pair but for sharing electron pairs is given by a single atom called electron pair Donor and atom which accept electron pair called electron pair acceptor . The bond is also known as semi polar or dative bond .
