$CH_3-CH(CH_3)-CH_3$ and $CH_3-CH_2-OMgBr$

Vedclass · Answer

(D) Grignard reagents $(R-MgX)$ react with compounds containing active hydrogen (like alcohols,$R'-OH$) to form alkanes $(R-H)$ and magnesium alkoxides $(R'-OMgX)$.The reaction of isobutyl magnesium bromide with absolute alcohol (ethanol) is as follows:$CH_3-CH(CH_3)-CH_2-MgBr + CH_3-CH_2-OH \rightarrow CH_3-CH(CH_3)-CH_3 + CH_3-CH_2-OMgBr$.The products are isobutane and magnesium ethoxide bromide.
