Consider the following reactions:
I. \( \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH} \stackrel{(A)}{\longrightarrow} \mathrm{CH}_{2}=\mathrm{CH}_{2}+\mathrm{H}_{2} \mathrm{O} \)
II.
\( \stackrel{(B)}{\longrightarrow} \mathrm{H}_{3} \mathrm{C}-\mathrm{CH}=\mathrm{CH}_{2}+\mathrm{H}_{2} \)
III.
Identify \( A, B \) and \( C \) in the given reaction.
(b) \( 85 \% \mathrm{H}_{3} \mathrm{PO}_{4}, \quad \mathrm{H}_{2} \mathrm{SO}_{4} ; \quad 20 \% \mathrm{H}_{3} \mathrm{PO}_{4} \), \( 440 \mathrm{~K} \quad 443 \mathrm{~K} \quad 358 \mathrm{~K} \)
(c) \( \mathrm{H}_{2} \mathrm{SO}_{4} ; \quad 85 \% \mathrm{H}_{3} \mathrm{PO}_{4}, \quad 20 \% \mathrm{H}_{3} \mathrm{PO}_{4} \),
\( \begin{array}{lll}\text { (d) } \mathrm{H}_{2} \mathrm{SO}_{4} ; & 20 \% \mathrm{H}_{2} \mathrm{SO}_{4} ; & 85 \% \mathrm{H}_{3} \mathrm{PO}_{4} \text {, } \\ 443 \mathrm{~K} & 358 \mathrm{~K} & 440 \mathrm{~K}\end{array} \) \( \begin{array}{lll}443 \mathrm{~K} & 358 \mathrm{~K} & 440 \mathrm{~K}\end{array} \)
