Question

Analyse the following reactions and arrange P, Q, R, T in increasing order of reactivity:
P sulphate + Q Q sulphate + P
Q sulphate +R → R sulphate +Q
R sulphate + T → T sulphate +R​

Answer 1

Answer:

qrt plus rrp pqe plus p equal to rrq

Answer 2

Explanation:

The Rosenmund reaction is catalyzed by palladium on barium sulphate. Barium sulphate reduces the activity of palladium due to its low surface area meaning it decreases the reducing power of palladium in order to prevent over-reduction of the acid.

So, BaSO

4

acts as a poison for Pd, not as a promoter for Pd

So, D is here correct answer
