Among halogens, the correct order of amount of energy released in electron gain (electron gain enthalpy ) is (a) F > Cl > Br > I (b) F < Cl < Br < I (c) F < Cl > Br > I (d) F < Cl < Br < I
Arrange F, Cl, O, and N in the decreasing order of electronegativity.
In which of the following option the order of arrangement does not agree with the variation of property indicated against it
a) Li<Na<K<Rb(increasing metallic radius)
b) B<C<N<O(increasing 1st ionisation enthalpy)
c)I<Br<Cl<F(increasing electron gain enthalpy)
d) Al3+<Mg2+<Na+<F-(increasing ionic size)
