         <title>Haloalkane has 4 reactions which are hydrolysis, formation of nitrile , formation of amines and elimition reaction. Alkene can form haloalkane by substitute the halogen.Hydrolysis will form alcohol, reagent in formation of nitrile is CN, reagent in formation of amines is NH3, reagent in elimination is ethanolic sodium hydroxide</title>
