Question

Draw the lewis structures for CH2I2, SI4, CSI2, AsBr2 -

1. which of the molecules is trigonal planar
2. which of the molecules violates the octet
3. which of the molecules has a sp3 hybridization
4. which of the molecules are polar

Answer 1

The Lewis structures for CH2I2, SI4, CSI2, and AsBr2-1 are provided. CH2I2 is polar and trigonal planar. SI4 violates the octet rule. CSI2 has sp3 hybridization.

Step-by-step explanation:

The Lewis structures for the given molecules are:

a) CH2I2: Lewis structure: H-C-I-I-H. The molecule is linear.

b) SiI4: Lewis structure: Si-I-I-I-I. The molecule violates the octet rule.

c) CSI2: Lewis structure: C-S-I-I. The molecule is trigonal planar.

d) AsBr2-1: Lewis structure: As-Br-Br. The molecule has sp3 hybridization.

All four molecules have polar bonds, but CH2I2 is polar due to its bent molecular structure.
