Final answer:
The molecular geometry of CH₂Cl₂ is tetrahedral.
Step-by-step explanation:
The approximate molecular geometry of CH₂Cl₂ is tetrahedral.
In CH₂Cl₂, the carbon atom is bonded to two hydrogen atoms and two chlorine atoms. The carbon atom has four electron groups: two bonding pairs and two lone pairs. According to VSEPR theory, the electron groups repel each other and tend to arrange themselves in a way that maximizes the distance between them.
Since the electron groups in CH₂Cl₂ are all bonding pairs and they repel each other equally, they push each other apart and form a tetrahedral arrangement around the central carbon atom. The molecule has a bent shape, with a bond angle of approximately 109.5°.
