draw abbr. structural formulae

Draw abbrivated structural formulae of the prouducts of the complete hydrolysis of lidocaine. identity the functional groups. 1st Diagram

Lidocaine is thought to bind to receptors in its methylated form. Identify in writing the atoms or groups that could be involved in its binding to a receptor via hydrogen bonding (only 1 example) and ionic reaction
2nd diagram

Give examples of the types of functional group that need to be present in the receptor sites in order for these forms of binding to take place (1 example from each binding)
I have my answers to this I would like to know if I am on the right track Thanks
