Organic Chemistry Reactions

Which functional group is present in $\mathrm{CH_3CH_2COOCH_3}$?

In an $\mathrm{S_N2}$ reaction at a stereocenter, what is the stereochemical outcome of the product?

Which reagent is most appropriate to convert a primary alcohol to an aldehyde without overoxidation to a carboxylic acid?

Predict the major product when 2-butene undergoes hydroboration-oxidation ($\mathrm{1) BH_3\cdot THF\ ;\ 2) H_2O_2, OH^-}$).

Which sequence best converts benzyl alcohol ($\mathrm{PhCH_2OH}$) to benzyl chloride ($\mathrm{PhCH_2Cl}$) with minimal rearrangement?

You need to synthesize trans-1,2-dibromocyclohexane from cyclohexene. Which condition gives the trans stereochemistry?

An $\mathrm{E2}$ elimination favors an antiperiplanar arrangement between the leaving group and the abstracted hydrogen.

In nucleophilic acyl substitution, a more reactive acyl derivative (like an acid chloride) will be less likely to undergo substitution than a less reactive derivative (like an ester).

A racemic mixture obtained from addition to a planar carbocation intermediate indicates that the mechanism involved an $\mathrm{S_N1}$ pathway.
