Chemistry 108 Quiz 1 Study Guide – Key Concepts, Formulas & Review Notes
What is organic chemistry? - ANS ✔✔branch of chemistry that deals with compounds that
contain at least 1 carbon-hydrogen bond
What is a hydrocarbon? - ANS ✔✔compounds that contain only carbon and hydrogen
What is biochemistry? - ANS ✔✔the study of chemical substances found in living systems and
the chemical reactions that are essential to the living cells
Most biomolecules contain...? - ANS ✔✔carbon atoms and they are organic compounds
Why is carbon a tetravalent - ANS ✔✔always forms 4 bonds (no more and no less)
Carbon atoms can form which types of bonds? - ANS ✔✔single, double, or triple bonds with
itself or other elements
Pure carbon has 3 allotropic forms, they are? - ANS ✔✔graphite, diamond, and
buckminsterfullerene
What is a allotropic form? - ANS ✔✔one or more physical forms of a element that occur is the
same physical state (solid, liquid, or gas)
Nonpolar covalent bonds for carbon form with? - ANS ✔✔C-C and C-H bonds
Polar covalent bonds formed between? - ANS ✔✔C and a more electronegative elements
, What do specific 3-dimensional shape depend on? - ANS ✔✔They depend on the type
(number) of bonds found on the carbon atom
Organic compounds often contain? - ANS ✔✔H,N,O,S, and P (elements of life) including C
What is the geometry of carbon? - ANS ✔✔tetrahedral
What are alkanes? - ANS ✔✔hydrocarbons that contain only carbon and hydrogen
How are alkanes connected? - ANS ✔✔every carbon is connected by a single carbon-carbon
bond
What is a saturated hydrocarbon? - ANS ✔✔when each carbon has maximum number of
hydrogens attached (full)
A saturated carbon can be what two things? - ANS ✔✔acyclic or cyclic
what is acyclic? - ANS ✔✔no rings, with a molecular formula of C(n)H(2n+2) (n is the number of
carbon atoms)
what is cyclic? - ANS ✔✔ring, with a molecular formula of C(n)H(2n) (n is the number of carbon
atoms)
What are the earth sources for alkanes? - ANS ✔✔natural gas, coal, and petroleum
What is the molecular formula for acyclic structures? - ANS ✔✔only the number of each atom
