Question

Part 1)

Classify each of the following as ionic or molecular. 

Drag the appropriate items to their respective bins.

Identify which of the following molecules can exhibit hydrogen bonding as a pure liquid. 

Check all that apply.

The hydrides of group 5A are NH₃, PH₃, AsH₃, and SbH₃. Arrange them from highest to lowest boiling point. 

Rank the molecules from highest to lowest boiling point. To rank items as equivalent, overlap them.

Indicate the major type of intermolecular forces that occurs between particles of the following: 

Drag the appropriate items to their respective bins.

Part 2)

The electronegativity of a bond is the difference between the electronegativity of the two atoms that make up the bond. Using the table of electronegativity values, determine if each bond is nonpolar covalent, polar covalent, or ionic.

Element	Electronegativity	Element	Electronegativity
F	4.0	S	2.5
O	3.5	Se	2.4
Cl	3.0	H	2.1
Br	2.8	Al	1.5
C	2.5	Na	0.9
I	2.5	K	0.8
