How to Draw a Lewis Structure
- Step 1: Find the Total Number of Valence Electrons.
- Step 2: Find the Number of Electrons Needed to Make the Atoms “Happy”
- Step 3: Determine the Number of Bonds in the Molecule.
- Step 4: Choose a Central Atom.
- Step 5: Draw a Skeletal Structure.
- Step 6: Place Electrons Around Outside Atoms.

Is CH3I tetrahedral?
The geometrical structure is a connected tetrahedral structure, like the one of CH3CH3. That’s because in this molecule, Iodine has 6 electrons that are not paired, and they affect the structure greatly, each filled orbital pushes away from each other like an atom, so Iodine forms a tetrahedral shape.
Is clf3 trigonal planar?
Chlorine trifluoride has 5 regions of electron density around the central chlorine atom (3 bonds and 2 lone pairs). These are arranged in a trigonal bipyramidal shape with a 175° F(axial)-Cl-F(axial) bond angle. The two lone pairs take equatorial positions because they demand more space than the bonds.
What is the bond angle of CH3I?
These are arranged in a trigonal bipyramidal shape with a 175° F(axial)-Cl-F(axial) bond angle. It is a dense, colorless, volatile liquid. Bond angle is 109.5 degrees.It is equal in every bond What molecules are a hydrogen bond ch3oh ch3cl ch3ooh hcl c4h8 ph3? B)
What the charges are on each side of a polar molecule?
A polar molecule has a positive electric charge on one side and a negative charge on the opposite side
How can you tell the difference between polar and nonpolar molecules?
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out
What is meant by a polar molecule?
A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule.
How do you know if a molecule is nonpolar?
Step 2: Identify each bond as either polar or nonpolar. (If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.) If there are no polar bonds, the molecule is nonpolar.
Does water attract nonpolar?
Nonpolar molecules, like fats and oils, don’t interact with water or form hydration shells. These molecules don’t have regions of partial positive or partial negative charge, so they aren’t electrostatically attracted to water molecules.
