Electrochemical series is series of elements arranged in increasing order of their reduction potential. E_(H^(+)|H_(2))=0. The metals abvoe H_(2) have reductioni potential, they are more reactive than hydrogen whereas metals below hydrogen are less reactive than H_(2). Reduction potentials of metal depends upon (i) sublimation energy (ii) ionization energy and hydration energy of ions. Which of the following is weakest reducing agent among alkali metals?

1.	Electrochemical series is series of elements arranged in increasing order of their reduction potential. E_(H^(+)\|H_(2))=0. The metals abvoe H_(2) have reductioni potential, they are more reactive than hydrogen whereas metals below hydrogen are less reactive than H_(2). Reduction potentials of metal depends upon (i) sublimation energy (ii) ionization energy and hydration energy of ions. Which of the following is weakest reducing agent among alkali metals?
