Benzene reacts with Chlorine gas in the presence of iron trichloride to yield hexachlorobenzene. However, when it reacts with fluorine gas, it forms a quinoid product (I would actually draw it for them - no need to know the name). Why the difference?

Fluorine is much more reactive than chlorine, even destroying the aromaticity. This is at the expense of the very strong C-F bonds (good orbital size and energy overlap) that are formed. C-Cl bonds are weake...

Explain the VSEPR Theory.

The acronym VSEPR is short for 'Valence Shell Electron Pair Repulsion'. Consequently, the VSEPR theory is about the repulsion effect of the most chemically important valence electrons and the influence of th...

Explain the reactions of CH3CH2Cl with the nucleophile NH3 and name the initial product formed.

Nucleophile- electron pair donor. If electron dense it's therefore attracted to a positive charge. A partial positive charge can be found on the C atom due to the electronegativity of chlorine. Therefore, CN...

What is the VSEPR theory?

(The answer really depends on the level of the student, hence more or less explanation might be needed.)The VSEPR (Valence Shell Electron Pair Repulsion) theory is used within chemistry to predict the geomet...
