Question

the image shows a lewis structure for vinyl chloride, which is used to make polyvinyl chloride (pvc), and pvc pipes used in construction engineering. pvc is the most commonly used polymer in construction engineering. pvc is chemically made by \polymerizing\ the monomer chemical, vinyl chloride. what is the molecular geometry at the carbon atom that is circled? tetrahedral, trigonal pyramidal, trigonal planar, linear, dont test me yet, i am trying to gain an understanding before attempting to answer this question.

Explanation:

Step1: Analyze bonding of circled carbon

The circled carbon in vinyl - chloride has 3 regions of electron density around it. It forms a double - bond with another carbon and single - bonds with two hydrogens.

Step2: Apply VSEPR theory

According to the Valence - Shell Electron - Pair Repulsion (VSEPR) theory, when a central atom has 3 regions of electron density, the molecular geometry is trigonal planar.

Answer:

trigonal planar
