Question

Complete the Lewis structures of these molecules by adding multiple bonds and lone pairs. Do not add any more atoms.

a) O₂
b) CO₂
c) HCN
d) H₂O

Answer 1

To complete the Lewis structures of the given molecules, we need to add multiple bonds and lone pairs. The Lewis structures for O₂, CO₂, HCN, and H₂O are as follows: O=O, O=C=O, H-C≡N, and H-O-H.

Step-by-step explanation:

To complete the Lewis structures of the given molecules, we need to add multiple bonds and lone pairs.

a) O₂: The Lewis structure for O₂ can be represented as O=O. Each oxygen atom has a double bond between them.

b) CO₂: The Lewis structure for CO₂ can be represented as O=C=O. There are two double bonds between the carbon and oxygen atoms.

c) HCN: The Lewis structure for HCN can be represented as H-C≡N. The carbon and nitrogen atoms are connected by a triple bond.

d) H₂O: The Lewis structure for H₂O can be represented as H-O-H. There is a single bond between the oxygen and each hydrogen atom.
