Iron bromide (FeBr2): ACTIVE. (The corresponding statement to each P-code can be found at the GHS Classification page.) Aggregated GHS information provided per 45 reports by companies from 4 notifications to the ECHA C&L Inventory. Each notification may be …

Fe + Br2 = FeBr3 is a Synthesis reaction where two moles of Iron [Fe] and three moles of Dibromine [Br 2] combine to form two moles of Ferric Bromide [FeBr 3]

Nov 25, 2013 · Take toluene and treat with either Br 2 in the presence of light, as per this procedure, or N-Bromosuccinimide (NBS) in the presence of a radical initiator + heat (or light) and one of the benzylic C–H bonds is replaced with C–Br.

Apr 18, 2018 · How do we install Cl, Br, or I on an aromatic ring? You may recall that alkenes react readily with Cl 2, Br 2, and I 2 to form dihalides. Benzene? Not so much. And when it does react with aromatic rings, it provides substitution rather than addition products. [Why?

-CH3 group is able to activate the benzene ring by hyperconjugation. So, -CH3 group shows o/p..directing influence on benzene ring.

1 Fe + 1 Br 2 = 1 FeBr 2 For each element, we check if the number of atoms is balanced on both sides of the equation. Fe is balanced: 1 atom in reagents and 1 atom in products.

Mar 25, 2019 · Statement I : Bromobenzene, upon reaction with Br 2 /Fe gives 1,4-dibromobenzene as the major product. Statement II : In bromobenzene, the inductive effect of the bromo group is more dominant than the mesomeric effect in directing the incoming electrophile.

Nov 25, 2019 · Toluene when treated with `Br_(2)//Fe`, gives p-bromotoluene as the major product because the methyl group

The benzene ring to which NH group is directly attached is activated for the attack of Br+ electrophile, as –NH group is ring activating due to +R effect. The ring to which C = O group is directly attached is deactivated towards electrophilic substitution.

IIT JEE 1999: Toluene, when treated with Br2/Fe, givesp-bromotoluene as the major product because the CH3 group (A) is para-directing (B) is meta-dire
