Consider the following statements and arrange in the order of true/false as given in the codes.
`S_1`:Interstitial compounds have high melting points, higher than those of pure metals.
`S_2`:Permagnate titrations in presence of hydrochloric acid are unsatisfactory.
`S_3`:`KMnO_4` does not act an oxidising agent in strong alkaline medium.
`S_4`:For `1^(st)` transition serise, the `E^()` value for `M^(2+)//M` indicate a decreasing tendency to form cation across the series.

Correct Answer - A
`S_1`:Due to strong interatomic forces.
`S_2`:Hydrochloric acid is oxidised to chlorine.
`S_3`:`MnO_4^(-)overset(OH^-)toMnO_4^(2-)`
`S_4:M^(2+)//M (E^(theta)//V)`-negative value decreases across the series.
