Question

R-OH+RMgX

Answer 1

The reaction produces an alkane ($R'H$) and an alkoxide-magnesium halide salt ($R-O^-MgX^+$).

Answer 2

The reaction between an alcohol ($R-OH$) and a Grignard reagent ($R'MgX$) is an acid-base reaction. The Grignard reagent acts as a strong base, abstracting the acidic proton from the alcohol's hydroxyl group. This results in the formation of an alkane ($R'H$) and an alkoxide-magnesium halide salt ($R-O^-MgX^+$). The general reaction is:

$$R-OH + R'MgX \xrightarrow{Anhydrous\; Ether} R-O^-MgX^+ + R'H$$
