The internet e.g. google AI says 3-ethyl-2-methylpentane has a chiral centre and can form R/S isomers, I say NOT, who is correct?

Apologies, something went wrong with C3H6O2 isomers image. It just shows 1-7, typical of what pre-university students should, but lots more isomers in reality!

Intellectual exercise, worked out as many isomers as possible (actual/theoretical) of formula C3H6O2 www.docbrown.info/page06/isome... >=33, very satisfying, x-ref errors on internet (particularly as I'm 80 in a week's time), corrected co-pilot & gemini lately, thanks & apology! You'll love C4H8O2!
