ALKYL HALIDE | CLASS 12TH | IMPORTANT NOTES | CHAPTER 10 (NCERT)

ALKYL HALIDE :


Alkyl halides find a variety of uses and applications in our everyday lives  which have been mentioned below: 


◈ Alkyl halides are used in labs as synthetic intermediate compounds.

◈They are used as cleansers for cleaning.

◈ Commercial uses of haloalkanes include its use in fire extinguishers.

PHYSICAL PROPERTIES

BOILING POINT:

                                              super tips to remember 

➜More the mass of alkyl halide more the boiling points of alkyl halide.
➜More the number of branches in alkyl halide less is the boiling point of alkyl halide.

⇛QUESTIONS
     
    Question 1). Arrange following in order of decreasing boiling                                point.
                                                               Methychloride(a),ethychloride(b),
               propylchloride(c),butylchloride(d)
      Answer 1). d>c>b>a


    Question 2).Arrange the following in order of increasing if                                    boiling point of isomers of butyl chloride.

 n-Butyl chloride (1-chlorobutane){A}
 tert-Butyl chloride (2-chloro-2-methylpropane){B}
 sec-Butyl chloride (2-chlorobutane){C}
 Isobutyl chloride (1-chloro-2-methylpropane){D}

          Answer 2). A>C>D>B      

SOLUBILITY:

 SUPER TIP

                               Boiling point is inversely  proportional to solubility
    
                    " BOILING POINT∝ 1/SOLUBILITY"
