Compound A has the molecular formula C11H12O. It gives a positive reaction with 2,4‐dinitrophenylhydrazine, but a negative result with a Tollens’ test. Treating compound A with LiAlH4 followed by dilute acid produces compound B, C11H14O, which can be resolved into enantiomers. When optically active compound B is oxidized by K2Cr2O7/H2SO4 solution, an optically inactive sample of compound A is produced. Heating compound A in basic hydrazine solution gives compound C, C11H14. Compound C does not decolorize a solution of bromine...

A compound of molecular formula C7H13Br is a tertiary bromide, is optically inactive, and has one primary carbon atom. C7H13Br is inert to catalytic hydrogenation. C7H13Br is reacted with another unknown compound. Thin-layer chromatography of the product mixture shows that two products are formed. GC analysis shows that the two products are formed in unequal amounts. Upon isolation from each other via distillation, both isolated products are optically inactive. Both products de-colorize molecular bromine. Answer questions a-c below. a. Based...
