Questions
Statement I : Al is highly electro positive metal in IIIA group
Statement II : ‘Al’ has lowest negative S.R.P in IIIA group
detailed solution
Correct option is B
Electronegativity order : B > Tl > In > Ga > AlElectropositivity order : B < Tl < In < Ga < AlElectropositivity order ∝ Metallic nature Reduction potential : Reduction potential is a measure of tendency to gain of electrons.More the positive reduction potential means more easy of gaining of electrons and more the electronegativity of that element [non metal].But "Al" is metal and hence it has high oxidation potential value and has low reduction potential value, means it has highest negative value.Similar Questions
