In which of the following reaction (s) H2SO4 does not act as an acid as well as an oxidant ?

A

C12H22O11 11H2OH2SO4 (Conc.) 12C\xrightarrow [ - 11 \mathrm { H } _ { 2 } \mathrm { O } ] { \mathrm { H } _ { 2 } \mathrm { SO } _ { 4 } \text { (Conc.) } } 12 \mathrm { C }

B

Zn + H2SO4¾® ZnSO4 + H2

C

Cu + 2H2SO4¾® CuSO4 + SO2 + 2H2O

D

NaHCO3 + H2SO4¾® NaHSO4 + H2O+ CO2

Answer

C12H22O11 11H2OH2SO4 (Conc.) 12C\xrightarrow [ - 11 \mathrm { H } _ { 2 } \mathrm { O } ] { \mathrm { H } _ { 2 } \mathrm { SO } _ { 4 } \text { (Conc.) } } 12 \mathrm { C }
