Answer:
★ Q. 1
◆OPTION D◆
Correct option is
A
It can act only as an oxidizing agent.
(A) Hydrogen peroxide can act as oxidizing as well as reducing agent.
For example, in acidic medium, it oxidizes ferrous ions to ferric ions.
2Fe2++H2O2+2H+→2Fe3++2H2O
In acidic medium, hydrogen peroxide reduces HOCl to chloride ion.
HOCl+H2O2→H++Cl−+H2O+O2
Thus, the option A is incorrect.
(B) It decomposes on exposure to light to form water and oxygen.
2H2O2⇌2H2O+O2
Thus, the option (B) is correct.
(C) It has to be stored in plastic or wax, lined glass bottles in dark to prevent its decomposition.
Thus, the option (C) is correct.
(D) It has to be kept away from dust as it decomposes in presence of dust.
Thus, the option (D) is correct.
★Q.2
◆OPTION A◆
Correct option is
D
ICl
ICl is an interhalogen compound. It contains two atoms of different electronegativities. Hence, the bond is polar.
The molecules of chlorine bromine and iodine contain atoms of same electronegativity and they contain non polar bonds.
Hence, ICl is most reactive.
