Which is not stable under ambient condition?
D.
Copper (I) compounds are aqueous solution and undergo disproportionation. 2Cu+ ➔ Cu2+ + Cu. The greater stability of (aq.) than (aq.), is due to much more negative undefined(aq.) than (aq.) which compensate for the second ionisation enthaply of Cu.

It is less basic than NH3.
Electronegativity of PH3 >NH3.
It does not show reducing properties.
