(S)-2-butanol reacts with potassium dichromate (K2CrO4) in aqueous sulfuric acid to give A (C4H8O). Treatment of A with ethylmagnesium bromide in anhydrous ether gives B (C6H14O). Draw the structure of B.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
