Grignard S Reagents And Their Uses

Standard electrode potential refers to the tendency of a metal to lose electrons and form positive ions (oxidation). A positive standard electrode potential means the metal has a greater tendency to be reduced than oxidized.
Let's go through the options:
- (A) Titanium has a negative standard electrode potential, indicating it prefers to oxidize and is not the correct answer.
- (B) Vanadium also has a negative standard electrode potential, meaning it is more likely to lose electrons than to gain them.
- (C) Iron has a negative standard electrode potential, meaning it tends to be oxidized and is not the correct answer.
- (D) Copper has a positive standard electrode potential, meaning copper has a greater tendency to be reduced (gain electrons) than oxidized. This makes it the correct answer.
- (E) Chromium has a negative standard electrode potential, meaning it tends to be oxidized rather than reduced.
Thus, the correct answer is Copper.
