Solution
\[\begin{array}{cc}
\phantom{...............}\ce{OMgBr}\\
\phantom{......}|\\
\ce{CH3 - CH - MgBr + HCHO -> CH3 - CH - CH2 ->[H2O] CH3 - CH - CH2OH + Mg(OH)Br}\\
|\phantom{....................................................}|\phantom{...................................}|\phantom{..............................}\\
\ce{CH3}\phantom{..............................................}\ce{CH3}\phantom{.............................}\ce{CH3}\phantom{...........................}\\
