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

Answer: 4-Methyl-2-pentanol

Step-by-step explanation:

I am assuming that the missing part after "then" with comma is H3C-C=O with another H bonded to the Carbon.

I added an image that shows how to work it through. It gives us 4-Methyl-2-pentanol.

Answer 2

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.
