Vedclass · Answer

(B) An electrophile is a reagent that can accept an electron pair in a chemical reaction.$H_2O$,$NH_3$,and $ROR$ (ethers) contain atoms with lone pairs of electrons,making them nucleophiles.$SO_3$ (sulfur trioxide) has an electron-deficient sulfur atom because the electronegative oxygen atoms pull electron density away from it,allowing it to accept an electron pair.Therefore,$SO_3$ is an electrophile.
