A-Level Chemistry Van der Waals forces

1. True

2. False

1. True

2. False

1. An hydrogen atom with an additional electron, a lone pair of electrons on a highly electronegative atom on another molecule

2. An electro deficient hydrogen, positive ion

3. An electron deficient hydrogen, a lone pair of electrons on a highly electronegative atom on another molecule

4. An electron deficient hydrogen, a lone pair of electrons on a highly electronegative atom on the same molecule

1. London forces

2. Ionic bonds

3. Permanent dipole interactions

4. Hydrogen bonds

5. Permanent-Induced Dipole

1. False, because, when bonded with Nitrogen, the hydrogen atom will not be electron deficient

2. False, because in Ammonia, Nitrogen does not have a lone pair of electrons

3. True, because, when bonded with Nitrogen, the hydrogen atom will be electron deficient and Nitrogen has a lone pair of electrons

4. True, because the bond between a Hydrogen atom and a Nitrogen atom is a covalent bond

1. True

2. False

1. be electron deficient

2. have excess negative charge due to the presence of additional electrons

3. be perfectly neutral because of the covalent bond

1. Strong forces

2. Permanent forces

3. Dispersion forces

1. True

2. False

1. weak, permanent dipole - permanent dipole interactions

2. strong, permanent dipole - permanent dipole interactions

3. strong, permanent - induced dipole

4. weak, permanent - induced dipole
