1.   Any molecule with this group attached to a carbon atom is called an alcohol.

2.   In diamonds, the carbon atoms are packed in a tetrahedral pattern which is extremely stable.

3.   In graphite the carbon atoms are arranged in flat hexagons layered on top of each other.

4.   In this group of ions the carbon atom is surrounded by three oxygen atoms in a planar triangle.

5.   The two substances differ from each other only in the geometric pattern with which the carbon atoms are packed.

6.   This leaves one electron on each carbon atom unaccounted for.

7.   In graphite sheets, carbon atoms bond together in rings.

8.   Number the carbon atoms from the end nearest the double bond.

9.   Primary alkanols have no more than one alkyl group attached to the carbon atom linked to the -OH group.

10.   Secondary alkanols have two alkyl groups attached to this carbon atom.
