Question

Select an appropriate reagent III and IV for the above reaction.

• A. $( III ) \rightarrow H _{2} O / H ^{+}( IV ) \rightarrow H _{3} PO _{2} / H _{2} O$
• B. $( III ) \rightarrow H _{2} O \quad( IV ) \rightarrow H _{3} PO _{2}$
• C. $( III ) \rightarrow H _{2} O / H ^{+}( IV ) \rightarrow H _{3} PO _{2}$
• D. $( III ) \rightarrow H _{2} O \quad( IV ) \rightarrow H _{3} PO _{2} / H _{2} O$

Answer 1

Answer: (A)

$III \rightarrow H _{2} O / H ^{+}\,\,\,IV \rightarrow H _{3} PO _{2} / H _{2} O$
