Main Question or Discussion Point

Hey, so I saw in my book that it used H2SO4 reacted with an alcohol to protonate it ( makes sense). But sometimes it uses diluted H2SO4 in warm and other times it will be H2SO4 in heat. I was just wondering, what difference do reaction hold?

What seems odd is that water is formed anyway in the protonation of alcohol, so why use diluted H2SO4?

What is the protonated alcohol used for? Same thing each time, or different reactions? If different - is it in any way strange that different reactions require different conditions?

Different reactions require different conditions. Sometimes conc. H2SO4 just screws up the reactants and sometimes diluted H2SO4 is just not enough or the reaction needs absence of water
