For each of the pairs of compounds below, determine which compound would be more soluble in hexane (C_6H_{14}) and explain your choice. \ A.\ Br_2 \text{ or } HBr\ B.\ CH_3CH_2OH \text{ or } CH_3OCH_3\ C.\ CS_2
(n=1893, representing a 316% increase) and complex PCI (n=999, increasing by 167%), the risk associated with 1-month DAPT compared to 12-month DAPT remained statistically insignificant for the primary endpoint, specifically for HBR cases (501% vs 514% ) and non-HBR cases (190% vs 202...
Explain why solutions of HBr in benzene (a non-polar solvent) are non-conductive, while solutions of HBr in water (a polar solvent) are conductive. Why would benzene boil at 100 degrees C instead of 80 degrees C? Why is stearic acid soluble in ethanol? Why is it not soluble in water...

NATURE COMMUNICATIONS | DOI: 10.1038/ncomms7445 ARTICLE silica gel may accelerate the hydrolysis of the silyl ether and thus led to a rapid aromatization along with release of HBr. Notably, when a single equivalent of 8 was used for the D-A reaction, a bromonaphthoquinone was readily prepared...
1- bromobutane is a primary alkyl halide, and may be synthesized by the acid-mediated reaction of a 1-butonaol with a bromide ion as a nucleophile. The proposed mechanism involves the initial formation of HBr in situ, the protonation of the alcohol by HBr, and the nucleophilic displacement ...
The reactions of primary and secondary alcohols with HCl require the presence of a catalyst, ZnCl2. With tertiary alcohols, the reaction is conducted by simply shaking the alcohol with concentrated HCl at room temperature. Constant boiling with HBr (48%) is used for preparing alkyl bromide. Good...
