why are the boiling points of alcohols higher than that of compounds with similar Mr?
there's hydrogen bonding between the O and H

what happens as the hydrocarbon chain of an alcohol gets longer?
influence of -OH bond on properties become less important so properties become more similar to the alkane

how does solubility change as alcohols get larger?
becomes less soluble

what conditions are needed to dehydrte alcohols to alkenes?
heated alumina catalyst, 300 degrees or reflux with conc. H2SO4

CH3CH2H2CH2Br + H2O

in which two ways can an alcohol undergo esterification?
using carboxylic acid (conc, H2SO4/HCl acid catalyst, reflux) or use acid anhydride

which mthod of turning an alcohol is better?
using an acid anhydride. theyre more reactive and give a higher yield of ester. the other method requires distilation and purification to separate ester
