CHEM 331 Exam 1 Material Test
Questions Fully Solved.
Constitutional isomers - Answer share the same molecular formula but have different
connectivity of atoms and different physical properties
Lone pairs - Answer a pair of unshared electrons
valencene electrons - Answer A formal charge occurs when an atom does not exhibit the
appropriate number of _______________.
individual atom, entire molecule - Answer An atomic orbital is a region of space associated
with _____________ while a molecular orbital is a region of space associated with
_____________.
sigma, lone pairs - Answer The geometry of small compounds can be predicted using valence
shell electron pair repulsion theory, which focuses on the number of ___________ bonds and
___________ exhibited by each atom.
intermolecular - Answer The physical properties of compounds are determined by
___________ forces, the attractive forces between molecules.
dipole moments - Answer London dispersion forces result from the interaction between
___________ transient and are stronger for larger alkanes due to their larger surface area and
ability to accommodate more interactions.
functional group - Answer A ___________ is a characteristic group of atoms/bonds that
show a predictable behavior.
Three - Answer When a carbon atom bears either a positive charge or a negative charge, it
will have __________ rather than four bonds.
out of, behind - Answer In bond-line structures, a wedge represents a group coming
___________ the page, while a dash represents a group __________ the page.
Single, octet - Answer When drawing curved arrows for resonance structures, avoid breaking
a __________ bond and never exceed _________ for second-row elements.
