Re: How do you put this into words?

C-O can be called carbon-oxygen bond.

C=O can be called carbon-oxygen double bond OR carbonyl group.

Are C-H bonds significantly polar? What about C-O?

^

and also, are C-O bonds many times more polar than C-H?

Sorry for the influx of questions lol, but I'm really confused

Re: Are C-H bonds significantly polar? What about C-O?

I've said that "alkanols contain 2 types of polar bonds, C-O and O-H, and these give it high MP/BP (the polarity of the C-H bond is insignificant by comparison)" blah blah blah in my notes (for the alkanol/ic acid dot point) and wanted to know if I was correct

Re: Are C-H bonds significantly polar? What about C-O?

I believe C-O is polar but the C-H is non-polar because the difference in electronegativity between carbon and oxygen is significant but between carbon and hydrogen, it is approximately equal (hence non-polar).

Okay then, got it

Thanks

Re: How do you put this into words?

So would it be correct to call it a "carbonyl bond" instead of "carbonyl group"?

I don't think so - the thing about "carbonyl group" is that it means C=O but not the bond specifically.

If you want to talk about the bond specifically, something like "C=O double bond" would be suffice.

Okey dokey! Thanks heaps for clearing things up

Re: Would the net ionic equation for this reaction be identical to the 'normal' react

But acetic acid is weak, so isn't it that we can't split it up into its separate ionic species since only a small percentage of molecules are actually split up like this? That's what my teacher said, but he likes to confuse us :/

But only the ones that are split up (ionised) will react.

I'm an idiot. Thanks for everything!
