Pick the WRONG pairing from the following
1. A3S
2. B4P
3. C2Q
4. E5R

Open in App

Solution

The wrong pairing is C2Q.
The correct pairing is C2T
Group V contains $B a^{2 +}, S r^{2 +} a n d C a^{2 +}$ ions. The group reagent is ammonium carbonate in presence of ammonium chloride and ammonium hydroxide.
The ions $B a^{2 +}, S r^{2 +} a n d C a^{2 +}$ are precipitated as carbonates which are insoluble in ammonium hydroxide.
