Draw the hemiketal obtained by addition of methanol to 3-methyl-2-hexanone This is what I got: 3-methyl-2-hexanone + CH3OH <-> CH3CH2CH(CH3)CH2C(OH)(CH3). But my answer is line angle formula because that's what the professor wants here's my line formula CH3 /\/\/ | OH I'...

How do you name an ester? I know they end in -anoate. But when you have one like CH3-C(double bond to O going downward)-O-CH3, would it be dimethyl anoate? Thanks.
