Question

I've got a molecule that I'm having trouble naming.

Answer 1

So do I choose the aldehyde as the longest chain and then how do I name the substituent?

Answer 2

I'm going to guess2-( (R) 3-hydroxy-3methylcyclopentyl)ethanal

Answer 3

Are you sure it's (R) ?

Answer 4

Ah, wait we must both be thinking of two different chiral centers.

Answer 5

I was thinking the one where the alcohol is attached but you're thinking where the ring is attached to the aldehyde chain I think.

Answer 6

actually, i dont remember the rules, BUT, i think you can also name this also as 3-[(R)-1-hydroxy-1-methylcyclopentyl]acetaldehyde?

Answer 7

Hmm, well I'm creating a key for an old Ochem professor I had for a test she's made where it's strictly IUPAC naming. Haha of course, she's made some really difficult ones that I don't remember.

Answer 8

yes, if it were a benzene ring, it could be treated as a substituent group. I would name the ring.
