When carboxylic acid reacts with organolithium reagents to give ketones, side reaction sometines occur. For example,
`HOCH_(2)CH_(2)overset(CH_(3))overset(|)(CH)CH_(2)CH_(2)overset(O)overset(||)COH underset("tetrahydro furan")overset((x) CH_(3)Li)rarr underset(H_(2))overset(NH_(4)Cl)rarr underset("Compound A 63%")(HOCH_(2)CH_(2)overset(CH_(3))overset(|)(CH)CH_(2)CH_(2)-overset(O)overset(||)C)-CH_(3)+ underset(37%)("Compound (B)")`
Value of (x) in above reaction is :
