WebYou could make DBr easily as a gas, but as soon as you dissolve it in water, it would become H2DO+ and Br-, and there’s nothing stopping the alkene from grabbing H+ instead of D+. You’d probably end up with 1/3rd of your reactant deuterated and 2/3rds normal.
In organic chemistry, syn- and anti-addition are different ways in which substituent molecules can be added to an alkene (R2C=CR2) or alkyne (RC≡CR). The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction. nelson hall homesWebCharles Adolphe Wurtz (French: [vyʁts]; 26 November 1817 – 10 May 1884) was an Alsatian French chemist.
