WebClick here👆to get an answer to your question ️ Reaction of Br2 with Na2CO3 in aqueous solution gives sodium bromide and sodium bromate with evolution of CO2 gas. The number of sodium bromide molecules involved in the balanced chemical equation is: WebA) all the carbons are sp2 hybridized, so there is considerable angle strain. B) The C-C bonds are formed by overlap of p-orbitals, so the 90º angle results in large angle strain. C) The cyclic overlap of bonding orbitals results in anti-aromaticity destabilization. D) The five C-C bonds have eclipsing strain. D. WebJan 23, 2024 · The electrophilic substitution reaction between benzene and sulfuric acid.
