For the reaction \( A \rightarrow \) products,
The reaction was started with 2.5 mol L\(^{-1}\) of A.
Consider the following electrochemical cell at standard condition. \[ \text{Au(s) | QH}_2\text{ | QH}_X(0.01 M) \, \text{| Ag(1M) | Ag(s) } \, E_{\text{cell}} = +0.4V \] The couple QH/Q represents quinhydrone electrode, the half cell reaction is given below: \[ \text{QH}_2 \rightarrow \text{Q} + 2e^- + 2H^+ \, E^\circ_{\text{QH}/\text{Q}} = +0.7V \]
Consider the following compound (X):
The most stable and least stable carbon radicals, respectively, produced by homolytic cleavage of corresponding C - H bond are:
