Give the correct order of initials \( \mathbf{T} \) or \( \mathbf{F} \) for following statements. Use \( \mathbf{T} \) if statement is true and \( \mathbf{F} \) if it is false.
(I) Sulphide ions reacts with \( \mathrm{Na}_{2}\left[\mathrm{Fe}(\mathrm{CN})_{5}(\mathrm{NO})\right] \) to form a purple coloured compound
\( \mathrm{P} \) \( \mathrm{Na}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{5}(\mathrm{NOS})\right] \). In the reaction, the oxidation state of iron changes

W
(II) \( \mathrm{Pt} \) (IV) compounds are relatively more stable than \( \mathrm{Ni} \) (IV) compounds
(III) The welding of magnesium can be done in the atmosphere of Helium
(IV) \( \mathrm{LiAlH}_{4} \) on hydrolysis will give \( \mathrm{H}_{2} \)
(a) FFTT
(b) FTTT
(c) TFTF
