You will get a ketone if your starting molecule looks like this: . . . where R and R' are both alkyl groups. Secondary alcohols oxidise to give ketones. With aqueous pKa values of around 16–19, they are, in general, slightly weaker acids than water. With strong bases such as sodium hydride or sodium they form salts called alkoxides, with the general formula RO M (where R is an alkyl and M is a metal).
