Certain organic compound on combustion produces three gaseous oxides A, B and C. A and C turned lime water milky, B turned anhydrous C u S O 4 blue and C turned K 2 C r 2 O 7 solution green. The elements present in organic compounds are

TestHub · Accepted Answer

The elements present in organic compounds are C, H, S and their oxides are $C O_{2}, H_{2} O, S O_{2}$ respectively.
$C O_{2}$ turns lime water milky, water turns anhydrous copper sulphate blue and $S O_{2}$ being reducing agent can reduce $K_{2} C r_{2} O_{7}$ into green coloured $C r^{3 +}$ compound $(C r C l_{3})$ etc.
