Depiction of the molecule

The borane THF complex should not displayed with a covalent bond, generating charges on the oxygen and boron. But rather with an arrow, signaling a dative character, like in other borane complexes, eg ammonia borane complex. 2003:C1:FF45:DDC2:AD4C:DA5F:E13A:9E9F (talk) 11:19, 13 May 2023 (UTC)Reply

The difference between a dative bond and a "normal" covalent bond is just the conceptual origin of the electrons, not realy the actual facts of the structure itself. See Dative bond#Comparison with other electron-sharing modes for details and notation. But if we draw a plain line (rather than dative arrow), howver, we should be more consistent and have formal-charges written on the oxygen and boron atoms. DMacks (talk) 17:51, 13 May 2023 (UTC)Reply
Yes, this I support, if charges are omitted an arrow should be used. My original comment was just due to the possible misunderstanding by students, who see this O-B bond equivalent to a C-C, C-O, ... covalent bond. 134.102.86.48 (talk) 07:56, 15 May 2023 (UTC)Reply
