Question

Decide what kind of crystalline solid each element or compound in the table forms, and what kind of force holds the solid together. Then, rank the solids in order of decreasing melting point. That Is, select "1" next to the solid with the highest melting point, "2" next to the solid w highest melting point, and so on.

That is, choose 1 next to the substance with the highest boiling chemical formula or Lewis structure bolling point H :O: НН H :O: H-C-c--c-H(Chocse one Choose one) H-C-C- N-CH(Choose one) H :O: HC-C-O C H (Choose one) Choose one) 2

Answer 1

1) CH2O : molecular , dipole-dipole, 2

C : atomic , covalent bonding, 1

N2 : Molecular, dispersion, 3

2) B can form H-BONDING thus it's boiling point is high. F2 involve weak dispersion forces thus have least boiling point. C has high boiling point than A because of high molecular mass.

So,

A : 3

B : 1

C : 2

D : 4
