| \[{{S}_{1}}\]: Interstital compounds have high melting points, higher than those of pure metals. |
| \[{{S}_{2}}\]: Permanganate titrations in presence of hydrochloric acid are unsatisfactory. |
| \[{{S}_{3}}\]:\[KM\,n{{O}_{4}}\] does not act as an oxidising agent in strong alkaline medium. |
| \[{{S}_{4}}\]: \[KM\,n{{O}_{4}}\] on heating in a current of \[{{H}_{2}}\] gives MnO |
A) TTFT
B) TFFT
C) TFTT
D) FFTF
Correct Answer: A
Solution :
\[{{S}_{1}},\,{{S}_{2}},\,{{S}_{3}}\] are correct statements. \[KMn{{O}_{4}}\] acts as an oxidising agent in strong alkaline medium.
