2024年5月31日 · FeBr3 is an ionic bond, as it forms between a metal (Fe) and a nonmetal (Br) resulting in the transfer of electrons from Fe to Br. Is iron bromide ionic or covalent bond? Iron bromide, which has ...

2024年5月28日 · The main difference between FeBr2 and FeBr3 is the oxidation state of iron. In FeBr2, iron has a +2 oxidation state, whereas in FeBr3, iron has a +3 oxidation state.

2024年5月22日 · FeBr3 is neither a base nor an acid. It is a salt, specifically an iron(III) bromide compound.

2024年6月6日 · Yes, FeBr3 is an ionic compound. It is made up of iron (Fe) cations and bromine (Br) anions, which are held together by ionic bonds due to the transfer of electrons from iron to bromine.

2017年1月23日 · I failed to identify the rate determining step because of the coordination of the Lewis acid $\ce{FeBr3}$. Therefore, the second mechanism occurs at a higher rate compared to the first mechanism, so more 2-bromo- N -phenylacetamide is produced per unit time, which makes it the major product .

2015年6月18日 · I don't think polarization is the issue. Adding $\ce{FeBr3}$ is just to reduce the $\ce{Br-Br}$ bond strength, speeding up the reaction (attack of the aromatic ring on the bromine is part of the rate determining step, which is slow in the bromination of benzene).

2021年3月22日 · When you do aromatic substitutions, you usually see the major products with one substituent added. My question is why can't you add multiple substituents in one reaction? For example, the image below shows nitrobenzene reacting with $\ce{Br2}$ and $\ce{FeBr3}$ to add $\ce{Br}$ to the meta position. Why can't the reaction continue and add to the ...

2022年12月29日 · The electrophile could be changed through halogen displacement. Here, that would be chlorine reacting with $\ce{FeBr3}$, independently of the benzene, so the electrophile in subsequent reaction with benzene becomes bromine instead of chlorine. Since the chlorine could alternatively act as an electrophile first, you get a mixture of halobenzene ...

2016年8月5日 · The FeBr3 catalyzes the reaction between toluene and Br2 to form ortho and para bromotoluene. Catalysts are NOT consumed in the reaction though, which means the culprit of the rusty color is the catalyst (google iron(iii) bromide to view the color).

2024年5月28日 · The main difference between FeBr2 and FeBr3 is the oxidation state of iron. In FeBr2, iron has a +2 oxidation state, whereas in FeBr3, iron has a +3 oxidation state. This results in different ...
