Organic Chemistry Exam Questions with Correct Answer

Organic Chemistry - Answer-The branch of chemistry which deals with carbon compounds, including those with no relationship to life. Covalent Bond - Answer-Inter-atomic relationship created by the sharing of at least one pair of electrons. Saturated Hydrocarbon - Answer-Contain only only carbon-to-carbon single bonds. The most chemically inert of all organic compounds. Unsaturated Hydrocarbon - Answer-Contain carbon-to-carbon double or triple bonds. Atomic Structure of Carbon - Answer-Atomic Number = 6, Protons = 6, Electrons = 6, Atomic Weight = 12.0. Electrons in first energy level = 2; second energy level = 4. Carbon - Answer-An element that has the capacity to share four electrons in order to achieve a more stable configuration. Bonding: Carbon to Hydrogen or Halogens - Answer-Shares one electron. Bonding: Carbon to Oxygen or Sulfur - Answer-Shares up to two electrons. Bonding: Carbon to Nitrogen - Answer-Shares up to three electrons Halogens - Answer-Flourine (F), Chlorine (Cl), Bromine (Br), and Iodine (I). Hydrocarbon Molecule - Answer-Contains only carbon and hydrogen. Can be divided into aliphatic and aromatic classes. Substituted Hydrocarbon - Answer-One or more hydrogen atoms are replaced by another atom or group of atoms called a Functional Group. Aliphatic Hydrocarbon - Answer-A saturated hydrocarbon that contains only hydrogen (the maximum number) and carbon. Does not contain benzene ring. Aromatic Hydrocarbon - Answer-Contain at least one benzene ring or similar structural features. Benzene - Answer-Consists of a ring of six carbon atoms with alternating single and double carbon-carbon bonds. Alkanes - Answer-(CnH2n+2)
