CHEMICAL BONDING Pre-laboratory Assignment
1. Define electronegativity.
2. What factors are used to determine whether a molecule will be polar or nonpolar?
3. What factors are used to determine whether a bond will be polar or nonpolar?
4. Carbon atoms have four valence electrons. As a result they need four more electrons to obey the octet rule. These electrons can be obtained by sharing electrons with other atoms during covalent bonding. The combinations of covalent bonds that fulfill the octet rule for carbon in neutral molecules are as follows.
• four single bonds• two double bonds• two single bonds and one double bond• one triple bond and one single bond
a. Now let's think about oxygen atoms. How many valence electrons do oxygen atoms have?
b. How many more electrons do oxygen atoms need to obey the octet rule?
c. What are the combination of covalent bonds that fulfill the octet rule for oxygen?
