Question description

We had 3 colourless solutions Q, R & S. We also had an orange coloured solution that was called reagent X. We had to carry out tests with Q, R & S with reagent X, then with Fehling's solution and then finally with Sodium Hydrocarbonate. 

Here were the results I obtained:

Addtion of X:

Q - Orange/brown solution formed

R - Purple solution formed

S - Pale yellow solution formed

With Fehlings:

Q - Brick red ppt formed

R - Brick red ptt formed

S - No obseverable change

With Sodium Hydrocarbonate:

Q & R - No reaction

S - Gas evolved

I am looking for the identity of Q,R,S and reagent X
