W hich conclusions can you draw for its acidity (pKa) in comparison to phenol?| b) Draw all resonance forms of 3-hydroxybenzaldehyde and of the corresponding conjugate base. Which conclusions can you draw for its acidity (pKa) in comparison to phenol and 3-hydroxybenzaldehyde? c) Discuss the relative acidities of 2-hydroxybenzaldehyd und 4-hydroxybenzaldehyd.

Draw the products of each reaction, and state whether the reaction is faster or slower than a similar reaction with benzene.

Draw the structure of each conjugate base, and indicate which is more stable. Provide a brief explanation to support your choice.

Which ring in each compound is more reactive toward electrophiles?

Draw the reaction and choose the correct characterizations

Which compound? a or b and why

Please draw the products for each nucleophilic substitution reaction. If there is no product, state why.

For the following reaction scheme, match the correct reagent to each reaction (A, B, C, D and E).

Explain why electrophilic aromatic substitution in Pyrrole takes place at C-2 positions whereas, in Pyridine it takes place at C-3 position?
