Final answer:
The Lewis structures and molecular geometries of the given molecules are as follows: SO₂ (bent), ClI4 (square planar), BCl₃ (trigonal planar)
Step-by-step explanation:
The Lewis structures and molecular geometries of the given molecules are as follows:
a) SO₂: The Lewis structure of SO₂ has a central S atom bonded to two O atoms. The molecular geometry of SO₂ is bent or V-shaped with a bond angle of approximately 119 degrees.
b) ClI4: The Lewis structure of ClI4 has a central Cl atom bonded to four I atoms. The molecular geometry of ClI4 is square planar with bond angles of 90 degrees between the Cl-I bonds.
c) BCl₃: The Lewis structure of BCl₃ has a central B atom bonded to three Cl atoms. The molecular geometry of BCl₃ is trigonal planar with bond angles of approximately 120 degrees.
