<BRAND NEW VERSION>
1. Organic Chemistry - ANSWER ✓ subdiscipline of chemical
sciences focused on the element carbon and the compounds formed
by combining carbon with ~10-12 other elements.
2. Organic Compound - ANSWER ✓ covalently bonded compound
containing carbon (excluding carbonates and oxides).
3. Catenation - ANSWER ✓ preference of an element to bond with
another atom of the same element.
4. Valence - ANSWER ✓ number of bonds an atom will form its
valence (outermost) shell of electrons
5. Lewis Dot Diagram - ANSWER ✓ visual representation of only
the valence shell of an atom, "LDD".
6. Ionic Bonds - 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.
7. Covalent Bonds - ANSWER ✓ sharing of electrons between
elements with little to no difference in electronegativities.
,8. Pure Covalent Bond - ANSWER ✓ covalent bond between atoms
of identical electronegativities, form when difference is 0 or less
than 0.5.
9. Polar Covalent Bond - 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.
10. Bond Order - ANSWER ✓ number of bonds between a pair
of atoms in a molecule, higher bond order means more bonds.
11. Unsaturated Compounds - ANSWER ✓ possess 1+ multiple
bonds or a ring, meaning fewer bonds can be made with Hydrogen.
12. Site/Unit of Unsaturation - ANSWER ✓ a multiple bond in
an organic compound
13. Constitutional Isomers - ANSWER ✓ compounds with the
same molecular formula that have different connectivity between
the atoms in their structural formulae
14. Basic Recipe for Structure Formulae - 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.
15. Goal of molecular geometry - ANSWER ✓ minimize
repulsion forces between pairs of electrons within a molecule
, 16. Wedge Bond - ANSWER ✓ shows things projecting towards
us, out of the page
17. Dash Bond - ANSWER ✓ shows things projecting away
from us, into the page.
18. Molecular Geometry - ANSWER ✓ the shape assumed by
the positions of the atoms, or groups, bonded around an atom
19. Electron Geometry - ANSWER ✓ the shape assumed by
pairs of electrons themselves
20. What determines the number of bonds an atom can form -
ANSWER ✓ The number of unpaired electrons
21. Do lone pairs bond - ANSWER ✓ No
22. Ionic bond - ANSWER ✓ The transfer of a valence electron
to another atom
23. Cation - ANSWER ✓ Loses electron and becomes positive
24. Anion - ANSWER ✓ Gains electron and becomes negative
25. Formal charge - ANSWER ✓ Atoms that do not meet the
LDD bonding pattern and possess non-zero charge
26. Calculate formal charge - ANSWER ✓ Group number -
(Dots + Dashes)
27. Overall charge - ANSWER ✓ Sum of formal charges
