1A compound is aromatic when:
(Choose the best answer.)- AAll atoms in the ring are sp2 hybridised.
- BIt's conjugated π system has an odd number of pairs of π electrons.
- CAn unsaturated, cyclic compound has (4n + 2) π electrons in it's system.
2Which heteroatoms are commonly found in heterocyclic compounds?
- ANitrogen, oxygen, sulfur
- BOxygen, nitrogen, phosphorus
- CCarbon, oxygen, nitrogen
3Label the o, m, p positions correctly.
- Ap
- Bo
- Cm
4Label the heterocycles.
- Abenzene
- Bphenyl
- Cbenzyl
- Dphenol
5Benzene and benzene derivates are chemically unstable, but quite stable in the body.
- AVerdadero
- BFalso
6Phenols, unlike alcohols, are not [blank_start]amphiprotic[blank_end], but are actually [blank_start]weak acids[blank_end]. This is because they have a stabilised [blank_start]conjugate base[blank_end].
- Aamphiprotic
- Bweak acids
- Cconjugate base
- Dresonance structure
7The lone pair of electrons of the nitrogen in a pyrrole are free to act as a nucleophile.
- AVerdadero
- BFalso
8An imidazole can act as a base.
- AVerdadero
- BFalso
9Tautomers are isomers which can interconvert by the movement of [blank_start]protons and electrons[blank_end] while maintaining the same [blank_start]carbon skeleton[blank_end].
- Aprotons and electrons
- Bcarbon skeleton
10Pyridine is a weak base.
- AVerdadero
- BFalso
11Choose the incorrect statement about B-lactam rings.
- AThey are energetically stable.
- BThey are 4 membered rings.
- CThey are strained.
