Help w carbonyls question?

Not sure on this
Attachment not found



*ugh it says attachment not found
here's the question:
Using HCN and a suitable carbonyl compound with molecular formula C3H6O, outline a mechanism for an addition reaction in which two isomers are produced.
Give the structures of the two isomers formed and state the type of isomerism shown.

yeah :/

i'll copy and paste it:

I did think that it'd be propanal, but i'm not sure on the structures of the products :s would you mind explaining?

There are only two carbonly compounds with this formula, propanone and propanal.

Reaction with HCN gives only one product with propanone, but two stereoisomers (enantiomers) with propanal.

The CN- ion can attack from either side of the planar CHO group.
