2. What is a dative covalent bond?

  • A bond vunerable to nucelophilic attack
  • A bond formed from the overlap of an empty orbital and a lone pair
  • A bond with a large difference in electronegativity between the two atoms
  • A bond where one atom donates 3 electrons

3. It doesn't conduct when solid, it has a high melting point, it is...

  • an ionic lattice
  • a giant ionic OR giant covalent structure
  • a metallic structure
  • a simple molecular structure

4. What is the most significant reason why HF has a higher boiling point than HCl?

  • The H-F bond has a higher bond enthalpy than H-Cl
  • Chlorine's larger number of electrons means more shielding of the nucleus therefore more repulsion between atoms in the H-Cl bond
  • HF can form strong hydrogen bonds between molecules, HCl cannot
  • HF is more polar so can create stronger permanent dipole-dipole forces

5. Which of these interactions is weakest?

  • Covalent bond
  • Hydrogen bonds
  • Permanent dipole
  • London Forces/induced dipoles
