Question

Which of the following statements is/are correct?
A. Chloropicrin `(C Cl_(3).NHO_(2))` can made cheapy for use as an insectide by the following reaction:
`CH_(3) NO_(2) + Cl_(2) rarr C Cl_(3) NO_(2) + HCl`
B. In a rocket motor fueled with butane `(C_(4) H_(10))`, 0.1 mol of butane requires `14.56 L` of `O_(2)` at `STP` for complete combustion.
C. A portable hydrogen generator utilises the reaction:
`(CaH_(2) + H_(2)O rarr Ca (OH)_(2) + H_(2)), 2.1 g "of" CaH_(2)` would produce `2.24 L` "of" `H_(2)` at `STP`
D. In the Mond process for purifying nickel, the volatile nickel carbonyl `[Ni(CO)_(4)]` is produced by the reaction. `Ni + Co rarr Ni (CO)_(4). 58.8 7g` of `Ni` utilises `89.6 L` of `CO` at standard conditions.

Answer 1

Correct Answer - A::B::C
a. `CH_(3) NO_(2) + underset(3 "mol")(3Cl_(2)) rarr underset(1 "mol")(C Cl_(3). NO_(2)) + 3HCl`
Volume of `Cl_(2)` at `STP = 3 xx 0.54 xx 22.4 = 33.6 L`
b. `underset(1 "mol")(C_(4) H_(10)) + underset(13//2 "mol")((13)/(2) O_(2)) rarr 4 CO_(2) + 5H_(2) O`
c. `underset((1 "mol" = 42 g))(CaH_(2) + 2H_(2) O) rarr Ca (OH)_(2) + underset(2H_(2))(2H_(2))`
d. `underset({:(1 "mol"),(= 58.7 g):})(Ni) + underset(4 "mol")(4CO) rarr Ni (CO_(4))`
Volume of `CO` standard conditions `= 4 xx 24.4`
`= 976 L`
Hence, (d) is wrong.
