I was thinking that acetaldehyde is a little more common than ispoentane,
thus probably more likely. But I like your suggestion

I'd rather use isopentane than acetaldehyde which is awkward
'orrible stuff which chokes you. I've used gallons of isopentane in
my work and there's probably a certain amount in petrol especially in
the winter. AFAIK it's the lightest liquid (density 0.626) and
lugging 25-litre cans of it around is rather nice compared with some
substances.
