Assertion (A): `Sn` reacts with `HCl` to produce `H_(2)` gas.
Reason (R ): `Sn` is a better reducing agent than `H_(2)` gas.

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct but `(R )` is incorrect.
D. If `(A)` and `(R )` are incorrect.

Answer

A

Explanation

Both `(A)` and `(R )` are correct, and `(R )` is the correct explanation for `(A)`.
`Sn+2HClrarrAnCl_(2)+H_(2)`
The oxidation potential of `Sn//Sn^(2+)` is greater than the oxidation potential of `H_(2)//2H^(o+)`. Hence, `Sn` is a better reducing agent than `H_(2)`.
