The "Br"^- will add to "C-3" and form 3-bromo-3-methylpentane There may be a small amount of product formed when the "H ... The mass of product formed in a reaction depends upon the mass of the limiting reactant. This is because no more product can form when the limiting reactant is all used up. Balanced chemical equations. A balance chemical equation shows the ratio in which substances react and are produced.

The reaction between magnesium oxide and carbon at 2000C to form magnesium metal and carbon monoxide is an example of the reduction of magnesium oxide to magnesium metal. It is useful to think about the compounds of the main group metals as if they contained positive and negative ions.3.3.3 The Selectivity of AF4-yne Toward Diels-Alder and Ene reaction Benzene is apparently not fast enough to capture all the AF4-yne when it is formed under Cram condition, thus, the above results could not provide the right information on

The selective fluorination of organic molecules has become increasingly important for the pharmaceutical and agrochemical industries, given that the presence of this atom enhances the lipophilicity and bioavailability of molecules.
