CHM 130LL Experiment 10 Name: PRE-LAB QUESTIONS 1. Explain the difference bctween a nonpolar covalent bond, a polar covalent bond, and an ionic Class number: bond 2. From its position in the periodic table, determine which atom in each pair is more electronegative: (a) N or O (b) S or O (c) S or P (d) N or Si (c) Ba or P 3. Distinguish the difference physical properties of ionic and covalent compounds. a) Are ionic compounds or covalent compounds usually soluble in water? Explain. b) Do ionic compounds or covalent compounds have a high melting point? Explain. 4. Define the term Extraction. 125

Explanation / Answer

Q no 1:-
The main point of difference between these three types of bonds is that the Nonpolar covalent bonds is that type of chemical bond where two atoms share a pair of electrons with each other.
While as in case of Polar covalent bonds pair of electrons is unequally shared between two atoms.
And in case of ionic bond complete transfer of electrons takes place.
