CHEM 219 Module 1 Exam Questions
With Correct Answers Scored A+
Organic Chemistry - ACCURATE ANSWER-subdiscipline of chemical sciences focused
on the element carbon and the compounds formed by combining carbon with ~10-12
other elements.
Unsaturated Compounds - ACCURATE ANSWER-possess 1+ multiple bonds or a ring,
meaning fewer bonds can be made with Hydrogen.
Site/Unit of Unsaturation - ACCURATE ANSWER-a multiple bond in an organic
compound
Constitutional Isomers - ACCURATE ANSWER-compounds with the same molecular
formula that have different connectivity between the atoms in their structural formulae
Basic Recipe for Structure Formulae - ACCURATE ANSWER-1. A backbone/skeleton
of carbon atoms.
2. Heteroatoms
3. Hydrogen atoms to complete valences of any carbon atoms.
4. Check structure with molecular formula.
5. Check for isomers.
Condensed Formulae - ACCURATE ANSWER-show atoms but few, or no, bonds and
indicate connectivity of atoms.
, Super-Condensed Formulae - ACCURATE ANSWER-collapse repetitions and typically
show no bonding. ex. (CH3)2CHCH2CH3
Organic Compound - ACCURATE ANSWER-covalently bonded compound containing
carbon (excluding carbonates and oxides).
Catenation - ACCURATE ANSWER-preference of an element to bond with another
atom of the same element.
Valence - ACCURATE ANSWER-number of bonds an atom will form its valence
(outermost) shell of electrons
Lewis Dot Diagram - ACCURATE ANSWER-visual representation of only the valence
shell of an atom, "LDD".
Ionic Bonds - ACCURATE ANSWER-complete transfer of one or more valence
electrons from one atom to another, form when difference in electronegativity is equal to
or greater than 2.
Covalent Bonds - ACCURATE ANSWER-sharing of electrons between elements with
little to no difference in electronegativities.
Pure Covalent Bond - ACCURATE ANSWER-covalent bond between atoms of identical
electronegativities, form when difference is 0 or less than 0.5.
Polar Covalent Bond - ACCURATE ANSWER-covalent bond between atoms of slightly
different electronegativities resulting in unequal sharing of electrons, form when
difference in electronegativities is greater than 0.5 but less than 2.
