5. Organic compounds differ from ionic compounds in that organic compounds generally have
1) Low solubility in water and are nonelectrolyte
2) Low solubility in water and are electrolytes
3) High solubility in water and are nonelectrolyte
4) High solubility in water and are electrolytes
6. Compared with the rate of an inorganic reaction, the rate of organic reaction is usually
1) Faster, because organic compounds are ionic substances
2) Faster, because organic compounds are molecular substances
3) Slower, because organic compounds are ionic substances
4) Slower, because organic compounds are molecular substances
7. Which best explains why there are more organic compounds than inorganic compounds?
1) The carbon atom readily forms covalent bonds with other carbon atoms
2) The carbon atom readily forms ionic bonds with other carbon atoms
3) The carbon atom readily combines with oxygen
4) The carbon atom readily dissolves in water
8. A carbon atom in any organic compound can form a total
1) 1 covalent bond 3) 3 covalent bonds
2) 2 covalent bonds 4) 4 covalent bonds
9. The four single bonds of a carbon atom are directed in space toward the corner of a
1) Regular tetrahedron 3) Square planer
4) Trigonal bipyramid
2) Regular octahedron
10. A student investigated samples of four different substances in the solid phase. The table is a
record of the behaviors observed (marked with an X) when each solid was tested.
Which substance has characteristics most like those of an organic compound?
1)A 2) B 3) C 4) D
