H2SO4-SO3-x2192-H2S2O7-Oleum-

Which of the following is chemical formula of Oleum?H2S2O8H2S2O5H2S2O4H2S2O7

H2SO4+SO3→H2S2O7(Oleum)

Which of the following is chemical formula of Oleum?
$H_{2} S_{2} O_{8}$
$H_{2} S_{2} O_{5}$
$H_{2} S_{2} O_{4}$
$H_{2} S_{2} O_{7}$

$H_{2} S O_{4} + S O_{3} \to H_{2} S_{2} O_{7} (Oleum)$
