Question

1.)Ionic Bondings usually have _________ melting points.
a.) low
b.) average
c.)high
d.) no

2.) Ionic Compounds are __________ conductors.
a.)good conductors
b.)poor conductors
c.)average conductors
d.) not any type of conductors

3) Van der Waal bonding is a type of
a.) intermolecular bonding
b.)polar bonding
c.)dipole bonding
d.) covalent bonding

4)Hydrogen bonding occurs with
a.) polar molecules
b.) dipole molecules
c.) Metals only
d.) hydrogen molecules

Answer 1

1) High melting points.

2) Good conductors of electricity. They are not necessarily good conductors of heat.

3) Intermolecular bonding. In particular, it is a kind of "gravitational bonding" based on mass alone

4) Polar molecules, but only if those molecules have covalently bonded H. Hydrogen bonding does not occu with hydrogen molecules (H2) LOL.
