The process is spontaneous at the given temperature, if
ΔH is +ve and ΔS is -ve
ΔH is -ve and ΔS is +ve
ΔH is +ve and ΔS is +ve
ΔH is +ve and ΔS is equal to zero.
Mesomeric effect involves
delocalisation of π- electron
delocalisation of σ- electron
partial displacement of electrons
delocalisation of π and σ- electron
Alkali metals have negative reduction potential and hence they behave as
oxidising agents
Lewis bases
reducing agents
electrolytes
