Give the correct order of initials or for following statements. Use if statement is true and if it is false.

(I)Sulphide ions react with Na2[Fe(NO)(CN)5] to form a purple coloured compound
Na4[Fe(CN)5(NOS)]. In the reaction, the oxidation state of iron changes

(II)In B2H6 vacant orbital takes part in hybridisation

(III) The welding of magnesium can be done in the atmosphere of Helium

(IV) LiAlH4 on hydrolysis will give H2.

Options:

Answer:
B
Solution:

(I) False: Oxidation state of iron does NOT change.

(II) True: In B₂H₆, boron is sp³ hybridized, and it has one vacant p-orbital.

(III) True: Helium is an inert gas and prevents oxidation during welding.

(IV) True: LiAlH₄ on hydrolysis produces H₂ gas.

 

Therefore, the correct order is FTTT.
