Using the strategies found in Chapter 4, draw
the Lewis structure and name the geometry for each
molecule.
a. H2S
b. SO2
(Sulfur is the central atom) Hint: because S and O are in the
same group on the periodic table, the structures for sulfur dioxide
and ozone will be closely related
c. N2O
(nitrogen is the central atom)
d. PF3
e. HCN (carbon is the
central atom)
f.
CF2Cl2 (carbon is the central atom)
For the molecules below, draw the Lewis structure, determine the
electron groups geometry, the molecular geometry, if the molecule
is polar or non-polar, and the symmetry point group.a) H2O.b)
SO2.c) I2.d) CCl4.e) CHCl3.f) CH2Cl2.g) H2C=CH2.h) Benzene.i)
XeF4.j) CHFClBr.k) NH3.l) PCl5.m) SF4.
1. Draw the Lewis structure, determine the molecular
geometry and electronic geometry, hybridization, and bond angles of
the following molecules: ICl2-, SnCl3-
2. Draw the energy diagram for aluminum and indicate
which ones are the valence shell orbitals. Then draw the
hybridization orbitals if the atom was sp hybridized
without using the table of Tolerance factors for normal
distributions, find a tolerance interval that gives two
sided 95% bounds on 90% of the distribution of packages of 95% lean
beef. Assume the data came from an approximately normal
distribution. where n=30, sample mean=96.2%, and standard
deviation= 0.8%.
a) number of valence electrons, lewis structure, electron
geometry, molecular geometry, bond angles, polar or non polar :
ICl4^-
B) lewis structure, electron geometry, molecular geometry, polar
or non polar, sketch or molecule: IO3^1, SCN^-, BH3
