Some Basic Principles Of Organic Chemistry Question 238
Question: Which series of reactions correctly chemical reactions related to iron and its compound
Options:
A) $ Fe\xrightarrow{Cl_2,,heat}FeCl_2\xrightarrow{heat,air}FeCl_2\xrightarrow{Zn}Fe $
B) $ Fe\xrightarrow{O_2,,heat}Fe_2O_4\xrightarrow{CO,600^{0}C}FeCl_3\xrightarrow{CO,700^{0}C}Fe $
C) $ Fe\xrightarrow{dil,H_2SO_4}FeO_4\xrightarrow{H_2SO_4,O_2}Fe{{(SO_4)}_3}\xrightarrow{heat}Fe $
D) $ Fe\xrightarrow{O_2,heat}FeO\xrightarrow{dil,H_2SO_4}FeSO_4\xrightarrow{heat}Fe $
Show Answer
Answer:
Correct Answer: B
Solution:
In [a], $ FeCl_3 $ cannot be reduced when heated in air.
In [c], $ Fe_2{{(SO_4)}_3} $ cannot be converted to Fe on heating; instead oxide(s) will be formed.
In [d], $ Fe_2SO_4 $ cannot be converted to Fe on heating; instead oxide(s) will be formed.
Hence [b] is correct.
