Haloalkanes contain halogen atom(s) attached to the sp3 hybridized carbon atom of an alkyl group whereas haloarenes contain halogen atom(s) attached to sp 2 hybridized carbon atom(s) of an aryl group. These are also known as alkyl halides and aryl halides respectively. Chapter wise Sessions. Skip to content. Boiling point. 0. of haloarenesare same as haloalkanes of same no. Finkelstein reaction: Alkyl chlorides or bromides when treated with NaI in dry acetone, alkyl iodides are formed. Conditions, Chapter 10 – Haloalkanes and Haloarenes Notes. Solubility: Although haloalkanes and haloarenes are polar yet they are insoluble in water. Boiling point generally increases with increase in the size of aryl group or halogen atom. Physical state, boiling & melting point are physical properties. This reaction is considered a useful method for the preparation of esters. of this page. Higher haloalkanes are colourless. State. on EduRev, you can check out Class 12 lecture & lessons summary in the same course for Class 12 Syllabus. For the same alkyl group, the boiling points of alkyl halides decrease in the order: RI> RBr> RCl> RF. Haloalkanes though polar but are insoluble in water as they do not form hydrogen bonding with water. Solubility.
