Question

Answer 1

Which of the following has the highest melting point

H2O
NACL
CH3OH
HOCH2CH2OH

Answer 2

Ionic has the highest melting point

Answer 3

The only Ionic compund in their is Nacl

Answer 4

@yadu123 correct, i'm going to post another one in this question

Answer 5

I thought it was B too

Answer 6

@Rushwr @yadu123 an much easier way to approach this question is it asks for melting point, that's going from solid to liquid. if you notice at room temperature all the other answer choices are in the liquid phase.

Answer 7

ok

Answer 8

the heat of vaporization does NOT depend on the following:

the external pressure
the strength of intermolecular forces
the mass of the molecules
the presence of hydrogen bonding

Answer 9

I dont know?

Answer 10

have you taken AP chem

Answer 11

I think for this question vaporization means going from liquid to gas so it's going to depend on like how strong the interactions are, if the interactions are stronger, it's going to require more energy to break those bonds and make it go from liquid to gas. if you notice, three of the answer choices are the same.

Answer 12
