As revealed by an Internet search, there is a marked difference in the German and English versions of the ER. The essential differences are

German: organic chemical compounds bearing more than one alcohol group on a carbon atom are not stable ^[1]; geminal diols tend to convert to a carbonyl group, giving off a water molecule in the process. ^[2]
English: all alcohols in which the hydroxyl group is attached directly to a double-bonded carbon atom become aldehydes or ketones.

A similar discussion entry appears in the German WP. Probably need an original source (horse's mouth, i.e. notes) to get this resolved. -- Canarris 11:12, 28 September 2010 (UTC)

A carbocation does NOT form, it's done in a concerted step.

^ [1], translated from this typical example of "Erlenmeyer-Regel" in German lit.

-I've made a similar discussion entry in the German WP article and hope to resolve this (at best with an original wording from Erlenmeyer himself!). — Canarris 10:44, 28 September 2010 (UTC)
