• Analyse the effects of the monosubstituents -OH, -Cl, -NO2 and -CH3 on the benzene ring and predict how they direct an attacking species (such as NO2¬+, CH3+, Br2 and SO3) to either the 2, 3 or 4 positions on the ring during substitution. Include within this section, the names of substituted benzene compounds, indicating how the name is based upon the functional group(s) present and the different positions on the benzene ring.

CH₃ (CH₂)₄ CH₃ +Br₂

Multi step synthesis of N- ethylethamide from ethanoyl chloride? To include the reagents, reaction conditions and also product- thanks

• Explain the accepted structure of benzene in terms of hybridisation, sigma and pi bonding, and delocalisation of electrons. Include examples of evidence (such as infrared, x-ray and thermochemical analysis) that support the structure of benzene as being very stable and regularly shaped. Include within your explanation why this evidence also disproves the originally suggested Kekulé structure for benzene, including reference to the bond lengths of C-C, C=C and those within benzene
