alleryWhich compound from the chapter's table has the highest melting point?
AZnCl2
BNaCl
CKCl
DMgO
Answer & Solution
Correct answer: D. MgO
1. The table lists melting points of several ionic compounds.
2. MgO melts at 2852 degrees Celsius, NaCl at 801, KCl at 772 and ZnCl2 at 290.
3. Comparing these, MgO has by far the highest value.
4. So MgO has the highest melting point in the table.
