# Why is Cyanidine soluble in water?

Cyanidine is not polar due to its make-up of only hydrogen atoms and carbon atoms, correct? But "like dissolve like", which means it would HAVE to be polar, or no? Is it then soluble solely because of its OH-groups being able to create hydrogen bonds with the water molecules, thereby making it miscible?

• And what is it this "polarity" your asking about? I wonder if you know what you're talking about. Apr 28 '17 at 18:26
• Well, I read it was soluble in water. It'd have to be polar, then? @Mithoron Apr 28 '17 at 18:41
• Then ask why it is soluble in water... Apr 28 '17 at 18:50
• @Mithoron Good point. I'll edit. Apr 28 '17 at 18:53
• You say cyanidine is not polar due to being made only of hydrogen and carbon, but then talk about it having OH groups. It has oxygen. Not only that but it is a charged species (also clearly shown on your structure). So that is two reasons why your initial suspicion of non-polarity because it is s simple hydrocarbon are wrong.

Cyanidine actually looks to me to be a rather highly polar compound. It's essentially a $\ce{C15}$ hydrocarbon having 5 hydroxyl groups and a formal positive charge.
