1)Which of the following compounds has the largest lattice energy:
LiF
LiCl
NaF
NaCl

2)Which of the following compounds has the most ionic character in its bonding:
CaBr2
GeBr4
KBr
GaBr3

3)Using the electronegativity table on page 364 of your text, which end of the B-N bond is negative?
B
N
neither
both

4)The O-H bond in a water molecule is:
nonpolar covalent
ionic
polar covalent
ionic covalent

My answers are:
1)LiF
2)KBr
3)N
4)polar covalent

I just want to be completely sure of these answers before submitting them, since I just get one opportunity to do so. If someone could check this, it would be deeply appreciated. Also, if something is wrong, please explain... Thanks

  1. #1 is a little confusing with the use of the word largest. I think it is common practice to list LiF as the largest lattice energy but technically it is the smallest number.
    Lattice energies are as follows:
    LiF = -1036 kJ/mol
    NaF = -923 kJ/mol
    LiCl = -853 kJ/mol
    NaCl = -787 kJ/mol
    Therefore, I think you answer to #1 is ok but do keep the negative in mind.

    2, 3, and 4 look ok to me.
