- Help ASAP Illustrate the resonance effect of the methoxy group -OCH3, on the structure of the benzene ring. Do this by writing all the possible resonance forms for methoxybenzene, including the hybrid. Based on your structures, explain how the presence of the -OCH3 group affects: (i) the reactivity of the benzene ring towards electrophilic attack; (ii) the orientation or point of attack of an incoming electrophilic reagent on the benzene ring.Hello! Could you help me understand the reaction mechanism for the ethylation of p-cyclopropyllphenol and its other reactants, AlCl3 and ethyl chloride, through an illustration? Please include the partial charges in each structure. Thank you in advance!You are a chemistry company's latest chemistry recruit and your first job is to prepare 2-methylcyclohexanol. The one key starting material you have been given is methylcyclohexane. Draw a scheme to take you from the starting material to the product outlining the reagents you would use for each step as well as the key organic product(s) formed from each step. [Note: You do not need to show mechanisms for any steps]
