Conversions related to
alkenes:
Following scheme will help you to
solve many conversions and it is also easy to remember. These conversions start
from alkenes and also end in alkenes.
The addition of HX obey Morkownikove’s
rule:
Which states
that Hydrogen goes to that Carbon which
have more Hydrogen in other word in an addition of unsymmetrical reagent to an
unsymmetrical alkene,negative part of adding reagent goes to that carbon in a
double bond which has least number of hydrogen atoms.
(This reaction is called ozonolysis and it is used to locate
the the position of double bond in a alkene.In ozonolysis one should keep in
mind that during the formation of product if the double bonded Carbon atom
consist of Hydrogen atoms it will lead to aldehyde ,and if the Hydrogen is
absent then it will lead to ketone .Symmetrical alkenes leads to symmetrical
number of aldehyde or ketone).
