Organic Chemistry Quests

What is the focus of organic chemistry?

• The study of nitrogen and its compounds

• The study of carbon and its compounds

• The study of oxygen and its compounds

• The study of hydrogen and its compounds

Which of the following is NOT an example of where organic compounds can be found?

• Fossil fuels

• Plants

• Animals

• Pure water

What defines a hydrocarbon?

• Compounds that contain only nitrogen and carbon

• Compounds that contain only oxygen and carbon

• Compounds that contain only hydrogen and carbon

• Compounds that contain only hydrogen and nitrogen

Are all organic compounds hydrocarbons?

• Yes, all organic compounds are hydrocarbons

• No, not all organic compounds are hydrocarbons

• Yes, but only if they contain oxygen

• No, organic compounds do not contain hydrogen

Why is carbon considered special in terms of its bonding capabilities?

• It has 2 valence electrons, so it can bond twice to achieve a stable octet

• It has 4 valence electrons, so it can bond 4 times to achieve a stable octet

• It has 6 valence electrons, so it can bond 6 times to achieve a stable octet

• It has 8 valence electrons, so it does not need to bond to achieve a stable octet

Which of the following is a property of organic compounds?

• They are good conductors of electricity.

• They react quickly due to ionic bonding.

• They have high melting and boiling points.

• They are insoluble and immiscible in water.

Why do organic compounds react slowly?

• Because they are metallic.

• Because they are covalent (nonmetal + nonmetal).

• Because they are ionic (metal + nonmetal).

• Because they are electrolytes.

Organic compounds typically have which of the following physical properties?

• High melting point and high boiling point

• Low melting point and high boiling point

• High melting point and low boiling point

• Low melting point and low boiling point

What does a molecular formula show?

• The physical state of a compound

• The # of molecules in a given volume

• The # of atoms of each element in a compound

• The types of bonds between atoms in a compound

What does a structural formula show about a chemical compound?

• Only the number of atoms of each element

• Only the arrangement of the atoms

• The physical state of the compound

• Both the number of atoms of each element and the arrangement of the atoms
