Rationalize this phenomenom based on what you know regarding cyclohexane derivatives and Sn2 reactions.
Calculate the molar mass (g/mol) of a gas whose root mean square speed is 796 m/s at 512 K.
we need to form a cyclohexanone with a methyl group at the 6 position and a 2,3-butanediol group (with both OH groups at the back (dashed lines)) at the 2 position. All carbons on the target need to come from the starting materials, but other than..
