Ester's Question (1 Viewer)

[Unwant3d]

ok the question stated "structural formual and name for the products"

did anyone draw the structual formula for Water as a product?
cause i just wrote H2O. seeing as i knew the "lewis dot diagram" of water not the "strutural" formula. ??

 

[nooj]

i did, cuz they hav had trick questions like that in my school exams

 

[Martyno1]

Yes I drew water

 

[Shrikar]

Shit, i wrote "H2O"

Well I drew H - O - H and H₂O ... dunno if it was H = O - H or H - O - H ....

The markers will be faced with a wide range of responses.

I drew the full ester clearly showing the ester linkage. I also drew the sturctual formula for water, stupid as it may seem. They did ask 4 it.

I made the bond longer than usual to show that the -OH bond was removed from the alcohol and the hexanoic acid gave up a hydrogen.

Yeah I did similar - put the linking 0 on an angle to show the point of connection and drew water as H - 0 - H. Felt a little silly about drawing water like that, though!

Better safe than sorry.
That's why I drew a single line right through my mistakes (or 'correct' answers) rather than scribble them out, but I know this only applies to Maths so far, where as long as markers can see correct working they can neglect your incorrect working and give you the marks you deserve.

 

[dwatt]

That's true. Gotta love that about maths. There's a kid in my class, who is very unconfident that he has the correct method. So he does about 3 methods and crosses them all out, because he deduces he can score more marks that way than leaving one (possibly incorrect) without scribble!

I just drew the ester. Didn't notice anything about the products. Hopefully I didn't screw it.

I did forget to mention water as a product though, damn it.

AAAh crap.

But I think you'll still get some marks.

Yeah but I was counting on them to make up for the multitude of others that I lost

I drew the reactants as well, figuring that because it was an equilibrium, they're still there in the 'products mixture'.... Hopefully I don't lose marks for that.

I drew the reactants too, so it made drawing the ester easier as it just involved just removing water after joining the ethanol and hexanoic acid.

Lol yeah, I had an ulterior motive. I just basically 'drew' the equation with structural formula.
