The three-dimensional structure of a generic molecule is given. Identify the axial and equatorial atoms in the three-dimensional structure.

Determine the following for the molecule Ozone (O3) type of bonds: shape: polarity: bond angle:

What shape are molecules that have three total atoms and 20 total valence electrons?

Explain what is wrong with each molecular geometry and provide the correct molecular geometry, given the numbers of lone pairs and bonding groups on the central atom. Match the words in the left column to the appropriate blanks in the sentences on the right. a bent a trigonal bipyramidal an octahedral a trigonal planar a square planar a trigonal pyramidal a tetrahedral a seesaw a linear In structure (a), four pairs of electrons give cause lone pair-bonded pair repulsions and would have Reset electron geometry. The lone pair would molecular geometry. Help In structure (b), five pairs of electrons give electron geometry. The lone pair occupies an equatorial position to minimize lone pair-bonded pair repulsions, and the molecule would have molecular geometry. In structure (c), six pairs of electrons give electron geometry. The two lone pairs would occupy opposite positions to minimize lone pair-lone pair repulsions, and the molecule would have molecular geometry.

What is the local molecular shape of the atom labeled "1?" What is the local molecular shape of the atom labeled "2?"  What is the approximate value of the bond angle labeled "3?"  What is the approximate value of the bond angle labeled "4?"

The number of electron domains found around the central atom is known as the... electron number bond number valence number atomic number steric number

On scratch paper, draw the Lewis structure for CCl4 then, referring to the structure, fill in the blanks: The electron-pair geometry is The molecular geometry is The bond angle is The molecular polarity is (polar or non-polar?)

Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.)
