What is obtained when alkyl halide is reacted with magnesium in presence of dry ether
Answers
grignard reagent A Grignard reagent or Grignard compound is a chemical compound with the generic formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH
3 and phenylmagnesium bromide (C
6H
5)−Mg−Br. They are a subclass of the organomagnesium compounds
Grignard compounds are popular reagents in organic synthesis for creating new carbon-carbon bonds. For example, when reacted with another halogenated compound R'−X' in the presence of a suitable catalyst, they typically yield R−R' and the magnesium halide MgXX' as a byproduct; and the latter is insoluble in the solvents normally used. In this aspect, they are similar to organolithium reagents.
Pure Grignard reagents are extremely reactive solids. They are normally handled as solutions in solvents such as diethyl ether or tetrahydrofuran; which are relatively stable as long as water is excluded. In such a medium, a Grignard reagent is invariably present as a complex with the magnesium atom connected to the two ether oxygens by coordination bonds.
Answer:an alkane is got
Explanation:
The alkyl halide reacts with two magnesium atoms that means two alkyl halides atoms will react which pull away the halides from the alkyl halides causing the carbon chain to double so if it was chloro methane it becomes ethane with two miles of magnesium chloride.
