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 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...

How to predict the bond angle and shape of a molecule of NH3

An atom of nitrogen has 5 valence electrons in its outer shell. Each hydrogen atom in ammonia bonds to the central nitrogen atom and contributes an electron each. This means there are 8 electrons in total on...

Back in 1950s, it was common to have as house cleaning items bleaching solution (containing sodium hypochlorite) and ammonia (used to remove, for example, hair dye stains). However, many people ended up in hospital after using them both, why?

Hypochlorite reacts with ammonia to yield chloramine and water. (emphasise to the students that hypochlorite is an oxidising agent, getting reduced to chloride ions). chloramine is a very toxic gas, since it...
