CHEM 113 Tutorial #3 Questions
Question 1. Fill in the with information regarding the electron group geometry, molecular shape, dipole
and hybridization on then central atom of the four molecules listed in the following table. Molecular
Formula ClF5
SCl2
BeF2
SeF5Cl Central atom electron
group geometry
(electron arrangement) Molecular shape Is the
molecule
polar? (yes or
no) Hybridization at the
central atom Question 2. Diamond and graphite are both materials composed solely of carbon atoms. However,
they exhibit dramatically different properties. Diamond is the hardest material known, whereas
graphite is soft and shears easily (that’s why it is used in pencil lead). The difference in properties
is related to the structures of these materials. In diamond, each carbon atom is bonded to four other
carbon atoms, which leads to a three-dimensional network of carbon-carbon bonds. In graphite,
each carbon is bonded to three other carbon atoms, which leads to a material composed of carbon
sheets (two-dimensional layers) that are stacked on top of each other. Explain the differences in
the structures of diamond and graphite using arguments based on VSEPR theory, orbital
hybridization and molecular orbital theory (hint: you may want to look at the part of the notes that
describes how the hybrid orbitals on carbon determine the geometry in ethene). Question 3: Indicate all the functional groups on the following two molecules. Question 4. i) name the following compounds, including whether the chiral centre is “R” or “S”. CH2-CH3 a) C H CH3 Br OH b)
CH2-CH3 C H CH3-CH2-CH2 ii) Name the following compounds, including whether the isomer is E or Z. a) CH3 CH2-CH3
C Br b) H C F C
CH2-CH2-Cl Br C
CH2-CH2-Cl
