Answer:
d) Ni < Co < Fe < Zn < Al
Explanation:
electronegativity of Aluminium 1.6
electronegativity of Zinc 1.7
electronegativity of iron 1. 83
electronegativity of Cobalt 1.88
electronegativity of Nickel 1.91
As the electronegativity of aluminium is lower as compared to other, so it will have high tendency to easily lose electron and that is why Aluminium is more reactive than the other mentioned
Hydro- meaning Hydrogen.
Carbon- meaning Carbon.
Hydrogen and Carbon. Carbon atoms form the framework, and Hydrogen atoms attach to them in many different configurations.
