(a) Interpretation: The intramolecular alkylation product formed from given reactants is to be drawn. Concept introduction: Protonation of an alkene forms a carbocation. This carbocation acts as an electrophile in a Friedel-Craft alkylation. The carbocation is generated in the presence of strong acid.

How to measure distance and calculate rate
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
