What kind of bond is CH₃Cl?
Answer:
The molecule CH₃Cl is known as chloromethane or methyl chloride. Understanding the type of bonding present in CH₃Cl requires examining its structure and the nature of the atoms involved.
Structure of CH₃Cl
CH₃Cl consists of:
- One Carbon (C) atom
- Three Hydrogen (H) atoms
- One Chlorine (Cl) atom
Each hydrogen is single bonded to the carbon atom, and the chlorine atom is also single bonded to the carbon atom. Let’s delve into the nature of these bonds.
Types of Bonds in CH₃Cl
-
C-H Bonds (Carbon-Hydrogen Bonds):
- These are covalent bonds.
- Covalent bonds arise when two atoms share their electrons. In a C-H bond, electrons are shared between carbon and hydrogen.
-
C-Cl Bond (Carbon-Chlorine Bond):
- This is a type of polar covalent bond.
- Electronegativity, which is the tendency of an atom to attract electrons, plays a critical role in determining bond types. The electronegativity difference between carbon (2.55) and chlorine (3.16) causes the electron sharing to be unequal. Chlorine attracts the shared electron pair closer to itself, creating a dipole moment.
- Therefore, in CH₃Cl, the C-Cl bond is polar covalent due to the significant electronegativity difference between carbon and chlorine.
Polarity of CH₃Cl
- Dipole Moment: The presence of chlorine with a higher electronegativity generates a dipole moment, making the molecule polar. The molecule exhibits a vector representation of charge separation, denoted as \delta^- (delta minus) on chlorine and \delta^+ (delta plus) on carbon.

In this structure, each hydrogen (H) creates a bond with carbon (C), while chlorine (Cl), due to its higher electronegativity, draws electrons closer to itself, resulting in a polar covalent bond.
Summary:
- CH₃Cl contains polar covalent bonds due to the C-Cl bond.
- The molecular structure leads to a polar molecule with a distinct dipole moment.
- C-H bonds are nonpolar covalent due to small electronegativity differences.
