Chapter 20, Problem 40P

Give structures for compounds R-W:

$\begin{array}{l}\text{N-}Methylpiperidine\underset{}{\overset{C{H}_{3}I}{\to }}R\left(C_7{H}_{16}NI\right)\underset{H_{2}O}{\overset{A{g}_{2}O}{\to }}S\left(C_7{H}_{17}NO\right)\underset{heat}{\overset{\left(-H_{2}O\right)}{\to }}\\ T\left(C_7{H}_{15}N\right)\underset{}{\overset{C{H}_{3}I}{\to }}U\left(C_5{H}_{18}NI\right)\underset{H_{2}O}{\overset{A{g}_{2}O}{\to }}V\left(C_8{H}_{19}NO\right)\\ \underset{heat}{\overset{}{\to }}W\left(C_5{H}_8\right)+H_{2}O+{\left(C{H}_3\right)}_{3}N\end{array}$
