A) To learn how gases interact with one another.
B) To understand molecular orbital theory and it's uses in industry.
C) To learn about lattice energies in solid state materials.
D) To learn about 3D shapes of molecules.
2)What does the acronym VSEPR represent?
A) Valence Shell Electron Pair Repulsion.
B) Valence Shell Excitation Probability Response.
C) Valence Supposition Electron Probability Ratio.
D) Viscous Solutions Expell Proportional Resistance.
3)Which of the following best explains VSEPR theory?
A) Atoms take up real space.
B) Determining the Lewis Dot structure is essential in determining the molecular shape.
C) All are correct.
D) Loan pairs of Electrons influence the shape of a molecule.
4)Which of the following correctly defines Valence Bond Theory?
A) A theory that describes how the nuclei repel one another.
B) A theory that describes how inter-atom bonding occurs.
C) A theory that describes electrons in the inner orbitals of atoms.
D) A theory that describes how atomic orbitals change when an atom becomes ionized.
5)How many lone pairs of electrons are on the central atom in the water molecule?
A) 0
B) 3
C) 1
D) 2
Explanation / Answer
1) Answer is
D) To learn about 3D shapes of molecules.
we write and read And see molecule in 2D form but actually molecule are exist in 3D structure . to get detail idea about 3D structure of molecule we study molecular geometry. and to know actual structure we use molecular model set .
2)Anser is
A) Valence Shell Electron Pair Repulsion.
in VSPER theory we study valance shell electron inraction
3) Answer is
C) All are correct.
molecule take up space they lie in space in 3D ,lewis dot structure also important to because lone pair of electron
influnce the shape of molecule .molecule occupy space in such way they have minimum repulsion
4)Answer is
B) A theory that describes how inter-atom bonding occurs.
VBT give information about how 2 or more atom form bond wth each other
5)Answer is
D) 2
there are 6 electron in outer shell of oxygen in which 2 are unpaired they form bond with two hydrogen and remaining 4 electron exist as 2 lone pair.
