I'm fairly new to Latex and I've been using chemfig to draw a couple of diagrams so far, but for this one I'm trying to do I've not found a way. I haven't used tikz before, but it seems to me that it would be the better option here. Nevertheless I can't find any example of what I'm looking for anywhere so I thought I would just ask.
Basically what I want to do is this:
But I haven't been able to come even close and don't have a single line of code to show for it. Can anyone help?
EDIT: I've very clumsily thrown together this following code, which is kind of what I wanted, but I'm hoping there's a neater way to do it. Also I would very much like the arrows to touch/merge in some way.
\documentclass{scrartcl}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzpicture}
\node (a) at (0,0) {A};
\node (b) at (2,0) {B};
\draw[-latex,bend right] (a) edge (b);
\end{tikzpicture}\\
\begin{tikzpicture}
\node (c) at (0,0) {C};
\node (d) at (2,0) {D};
\draw[-latex,bend left] (c) edge (d);
\draw[-latex,bend left] (d) edge (c);
\end{tikzpicture}\\
\begin{tikzpicture}
\node (e) at (0,0) {E};
\node (f) at (2,0) {F};
\draw[-latex,bend right] (f) edge (e);
\draw[-latex,bend right] (e) edge (f);
\end{tikzpicture}\\
\begin{tikzpicture}
\node (g) at (0,0) {G};
\node (h) at (2,0) {H};
\draw[-latex,bend left] (g) edge (h);
\end{tikzpicture}
\end{document}
/documentclass{
and ending with\end{document}
would let us run things on our side and find the solution you see.
