Determine the Number of Bonding Groups in CH2Cl2

To determine the number of bonding groups in CH₂Cl₂, we need to analyze the molecular structure of the compound.

CH₂Cl₂, or dichloromethane, consists of one carbon atom (C) bonded to two hydrogen atoms (H) and two chlorine atoms (Cl). In chemical bonding, a bonding group refers to a single bond between atoms.

The carbon atom in CH₂Cl₂ forms four single covalent bonds: two with hydrogen atoms and two with chlorine atoms. Each of these bonds constitutes one bonding group. Thus, the total number of bonding groups associated with carbon in this molecule is:

• 2 (from the two C-H bonds)
• 2 (from the two C-Cl bonds)

Therefore, the total number of bonding groups in CH₂Cl₂ is 4.
