1.	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 theseries.
Answer» SOLUTION :`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.
