Hydrolysis of halogenoalkanes chemguide
WebThe hydrolysis of halogenoalkanes is a nucleophilic substitution reaction. In this investigation the nucleophile is water. If NaOH is used to hydrolyse the halogenoalkanes, … WebIntroduction. A Grignard reagent has a formula \ce {RMgX} where \ce {X} is a halogen, and \ce {R} is an alkyl or aryl (based on a benzene ring) group. For the purposes of this page, we shall take R to be an alkyl group. A typical Grignard reagent might be \ce {CH3CH2MgBr}. Grig nard reagents are made by adding the halogenoalkane to small bits ...
