Could someone tell me how to braille this? I have never seen this with the arrow in it and I can’t find anything that explains how to represent this. Picture in the attachments.
Aha! I found this symbol in 4.2.6 of the Chemistry Code. See Example 4.2.6-1 where they call this arrow “two covalent and one coordinate covalent bond.”
Your example includes two electron dot pairs as well.
