Nettet14. okt. 2011 · First you treat it with magnesium, and then you treat the Grignard with a strong acid. This gives you the alkane. You can also use this to introduce deuterium (D) into molecules! The first step is to make the Grignard reagent. The second is to treat that Grignard with a deuterated acid such as D2O. This gives you the deuterated alkane!

Nettet15. okt. 2024 · Deuterium oxide (D 2 O), aka “heavy water”, is the form of water that contains two atoms of the 2 H, or D, isotope. The term heavy water is also used for water in which 2 H atoms replace only some of the 1 H atoms. In this case, rapid exchange between the two isotopes forms twice as many “semiheavy” HDO molecules as D 2 O.. … NettetDeuterium H2 CID 24523 - structure, chemical names, physical and chemical …
