H2so4 as a nucleophile
WebI know if I react the alkene with cold conc. H2SO4 I get an alkyl hydrogensulfate which upon reaction with boiling water gives alcohol,but I can't understand the need for these conditions like what if we reverse them. ... (assuming that HSO4- is weaker nucleophile than water).So why don't we just add both sulphuric acid and water combined? ...

WebThe vapor pressure of H2SO4 is 0.001mmHg at 20 0 C. the pKa 1 and pKa 2 of H2SO4 are -2.8 and 1.9. so, from the value of pKa, we can say that it is a very strong acid. The viscosity of the acid is 26.7 centipoise (20 °C). The density of H2SO4 is, 1.8302g/cm 3. The molecular weight of sulfuric acid is 98.079 g/mol.
