Question

1. Which force below is the strongest intermolecular attractive force? a. Hydrogen bonding b. Ion-dipole forces c. Dipole-dipole forces d. London dispersion forces 2. Which force below increases in strength as the molecular weight of the compound. increases? a. Hydrogen bonding b. Ion-dipole forces c. Dipole-dipole forces d. London dispersion forces 3. Which compound below is not capable of forming hydrogen bonds? a. CH4 b. NH c. H20 d. HF 4. Which compound below has the highest boiling point? a. H20 b. H2S c. H2Se d. H2Te 5. Which element below has the highest boiling point? a. Kr b. F2 c. C12 d. Br2

Explanation / Answer

1) Hydrogen Bonding is the strongest force

2) London dispersion force depends on no of electrona and hence increases as the molecular weight increases

3) H bonding occurs when H is attached to highly electronegative atom such as N, O, F. Hence CH4 does not for H bond

4) H2O has highest boiling point as it has H bonding.
