Given below are a set of half-cell reactions (in acidic medium) alongwith their E° (in volt) values.

l2+2e- → 2l- E°= 0.54
Cl2+2e- → 2Cl- E°= 1.3
Mn+3 +e- →Mn+2 E°= 1.50
Fe+3+e- → Fe+2 E°= 0.7
O2+4H+4e →2H2O E°= 1.23

1.Among the following, identify the correct statement 

(1) Cl is oxidised by O

(2) Fe+2 is oxidised by iodine 

(3) I is oxidised by chlorine 

(4) Mn+2 is oxidised by chlorine

2. While Fe+3 is stable, Mn+3 is not stable in acid solution because 

(1) O2 oxidises Mn+2 to Mn+3 

(2) O2 oxidises both Mn+2 to Mn+3 and Fe+2 to Fe+3 

(3) Fe+3 oxidises H2O to O

(4) Mn+3 oxidises H2O to O2

3.The strongest reducing agent in aqueous solution is 

(1) I(2) Cl– (3) Mn+2 (4) Fe+2
