Why allyl chloride are more reactive than vinyl chloride towards nucleophilic substitution reaction? (5 marks)
Allyl chloride is more reactive than vinyl chloride towards nucleophilic substitution reaction because allyl cation is resonance-stabilized and vinyl cation is not.

Aromatic aldehydes are less reactive towards nucleophilic addition reaction.Answer.
Aromatic aldehydes are less electrophilic due to the M+ effect of aromatic ring. The partial positive charge is stabilized by pi electrons of the aromatic ring, which makes it less...

Aromatic aldehydes are less reactive towards nucleophilic addition reaction.
v) Aldol condensation cannot take place in the absence of α-hydrogen
Aromatic aldehydes are less reactive towards nucleophilic addition reaction because aromatic ring pulls electron density.Aldol condensation cannot take place in the absence of α-hydrogen because in the first step aldehyde...

fluoride is a good leaving group in aromatic nucleophilic substitution while it is poor leaving group in SN1 and SN2? Explain
Its high charge density makes it relatively unpolarizable. The leaving group needs to be polarizable to lower the energy of the transition state.

Analyse the effects of different monosubstituents on the benzene ring to predict further substitution position(s) of a reaction species on the benzene ring.
Experiments have shown that substituents on a benzene ring can influence reactivity in a profound manner. For example, a hydroxy or methoxy substituent increases the rate of electrophilic substitution about...

Mg H - Decrease in reactivity Cu Based ONLY of the position in the reactivity series, which element would you select for use in making containers to store acidic fruit juice? Explain your answer.
Since as we move from Mg to Cu, there occurs a decrease in chemical reactivity, copper does not react with dilute acids to produce hydrogen gas where as magnesium is...
