2. What is the bonding like in a benzene?
- Overlap of r-orbitals/ π bonds/ electrons above and below the ring.
- Overlap of p-orbitals/ π bonds/ electrons above and below the ring.
- Overlap of q-orbitals/ π bonds/ electrons above and below the ring.
3. How the benzene ring in the phenoxide ion is activated?
- lone/electron pair from O is delocalised into ring so increases π-electron density so attracted electrophiles more
- lone/electron pair from O is delocalised into ring so lowers π-electron density so attracted electrophiles less
- lone/electron pair from O is delocalised into ring so lowers π-electron density so attracted nucleophiles more
4. Phenol converted to sodium phenoxide C6H5O-Na+ choose a correct balanced equation for this reaction?
- C6H5OH + NaOH → C6H5O–Na+ + H2O
- C6H5OH + NaO → C6H5O+Na- + H2
- C6H5OH + NaOH → C6H4O–Na+ + O
5. The conditions required for nitration of benzene using nitric acid and sulphuric acid
- Temperature 30-40 and concentrated (acids)
- Temperature 50-60 and concentrated (acids)
- Temperature 10-20 and concentrated (alkalis)
