Question

What organic product would be formed from the reaction of 1-bromo-2-methylpropane (isobutyl bromide), (ch3)2chch2br, with mg, et2o, then , then h3o+?

Answer 1

The reaction of 1-bromo-2-methylpropane (isobutyl bromide), $(CH_3)_2CHCH_2Br$, with $Mg$, and $Et_2O$ results in the formation of an adduct of formula $(CH_3)_2CHCH_2MgBr$ known as grignard reagent, an organometallic reagent, which on reacting with $H_3O^{+}$ results in the formation of isobutane.

The reaction is shown in the image.
