हिन्दीUrea reacts with water to form A which will decompose to form B. B when passed through \( \mathrm{Cu}^{2+}_{(\text{aq})} \), deep blue colour solution C is formed. What is the formula of C from the following?
Correct answer · Option 1
\( [\mathrm{Cu}(\mathrm{NH}_3)_4]^{2+} \)
Explanation
Urea hydrolyzes with water to form ammonia (A and B), which forms a deep blue complex \( [\mathrm{Cu}(\mathrm{NH}_3)_4]^{2+} \) with \( \mathrm{Cu}^{2+} \).
