Urea reacts with water to form A which will decompose to form B . B when passed through Cu 2 + aq , deep blue colour solution C is formed. What is the formula of C from the following?
Options
- ACu NH 3 4 2 +
- BCu OH 2
- CCuCO 3 · Cu OH 2
- DCuSO 4
Correct answer
A. Cu NH 3 4 2 +
Step-by-step solution
NH 2 CONH 2 + H 2 O → CO 2 + NH 4 OH A NH 4 OH → Δ NH 3 B + H 2 O Cu + 2 aq + 4 NH 3 → Cu NH 3 4 C + 2 (deep blue)
