Some Basic Principles Of Organic Chemistry Question 238

Options:

A) $F e \overset{C l_{2},, h e a t}{\to} F e C l_{2} \overset{h e a t, a i r}{\to} F e C l_{2} \overset{Z n}{\to} F e$

B) $F e \overset{O_{2},, h e a t}{\to} F e_{2} O_{4} \overset{C O, 600^{0} C}{\to} F e C l_{3} \overset{C O, 700^{0} C}{\to} F e$

C) $F e \overset{d i l, H_{2} S O_{4}}{\to} F e O_{4} \overset{H_{2} S O_{4}, O_{2}}{\to} F e {(S O_{4})}_{3} \overset{h e a t}{\to} F e$

D) $F e \overset{O_{2}, h e a t}{\to} F e O \overset{d i l, H_{2} S O_{4}}{\to} F e S O_{4} \overset{h e a t}{\to} F e$

Show Answer

Answer:

Correct Answer: B

Solution:

In [a], $F e C l_{3}$ cannot be reduced when heated in air.

In [c], $F e_{2} {(S O_{4})}_{3}$ cannot be converted to Fe on heating; instead oxide(s) will be formed.

In [d], $F e_{2} S O_{4}$ cannot be converted to Fe on heating; instead oxide(s) will be formed.

Hence [b] is correct.
