Don think it could have been a straight line coz there was 5 carbons but only 4 carbon environments so I did 4 in a row then a methyl group on end and Ketone on 2nd carbon

That was an awesome paper.
Proud to say like the trolls in TSR exam threads it was a walk in the park.

Tsk, you always looked down at them, and now it's you.

It couldn't have been because the Carbon -13 NMR gave 4 carbon environments, but your one would only have 3 as it would be symmetrical

I talked about it being photodegradable. The thing that made me think that was the "technical terms spelt correctly". Photodegradable has been a 'spelling' mark on a previous paper.
