2. What is a dative covalent bond?
- A bond vunerable to nucelophilic attack
- A bond where one atom donates 3 electrons
- 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
3. Which of these is NOT describing the same shape as the others?
- Trigonal pyramidal
- Includes angle of 90
- Eg PCl5
- Three atoms are on the same plane
4. What is a pi-bond?
- The stronger bond in a double bond, with electron density trapped between nuclei
- The sideways overlap of two p-orbitals
- The end on overlap of two s-orbitals
- The end on overlap of two p-orbitals
5. What causes ice to be less dense than liquid water?
- Molecules pack more efficiently in the water liquid due to strong hydrogen bonds pulling molecules together at 180o of each other
- Hydrogen bonds between molecules in ice create an open and spaced "cage" structure, which breaks down on melting
- Molecules vibrate more when cold and thus move apart, making the solid less dense
- There are no intermolecular interactions between molecules as solids so the molecules drift apart
