Consider the following reactions A + NaCl + H2SO4 → CrO2Cl2 + Side Products CrO2Cl2(vapour) + NaOH → B + NaCl + H2O B + H+ → C + H2O The number of terminal ‘O’ present in the compound ‘C’ is _____.

1. 6
2. 5
3. 4
4. 7

Correct answer: 6

Solution

The compound 'C' is derived from the reaction involving 'B' and H+, which typically indicates the formation of a compound with multiple oxygen atoms. Given the reactions and the stoichiometry involved, the final compound 'C' contains six terminal oxygen atoms, making option A the correct choice.
