C(dia) & HF c. CH3NH2 & CH3F d. BCI; & PCIE e.C.H10 & C5H14 f.CS, & OBrz

Answer 1

a.

1. BaCl2- ionic compound CH2F2 - ionic compound

2. BaCl2- Ionic bonds CH2F2 - ionic bonds

3. BaCl2 will have higher attraction in solid and CH2F2 will have higher attraction in liquid

4. BaCl2 will have higher boiling point.

b.

1. C(dia) - Non-metallic compound HF- ionic compound

2. C(dia) - covalent HF- ionic bond

3. C(dia) will have higher attraction in solid. HF- liquid

4. C(dia) has high boiling point.

C.

1. CH3NH3 - Non-polar molecular substance CH3F- polar molecules substance.

2. CH3NH3- Covalent bonds, CH3F hydrogen bonding and covalent bonds

3. CH3NH3- liquid CH3F- gas

4. CH3NH3 has high boiling point.

D.

1. BCl3 non-polar molecular substance and PCl3 polar molecular substance

2. BCl3 - polar bonds PCl3- covalent

Pcl3 will have high boiling point.

2.
