Consider the following chart with ionic and covalent compounds shown.
| Ionic and Covalent Compounds | ||
|
Compound |
Melting Point ⁰C |
Boiling Point ⁰C |
|
W |
801 |
1465 |
|
X |
2852 |
3,600 |
|
Y |
0 |
100 |
|
Z |
113 |
184 |
Based on the data, which compounds would you classify as ionic or covalent and why?
| A |
Compound Y is ionic because its’ melting and boiling points are low. |
|
| B |
Compound Y and Z are covalent because their melting and boiling points are low. |
|
| C |
Compounds W, X, and Z are ionic because their melting and boiling points are high. |
|
| D |
Compounds W, X, and Z are covalent because their melting and boiling points are high. |
Covalent bond is formed by sharing of electrons while ionic bond is formed by combination of oppositely charged ions.
Covalent compounds have low m.p. and b. p. than ionic compounds.
Ionic compounds are crystalline and have very high melting point.
e. g. NaCl, its melting point is 800°C.
