An alkene "A" on ozonolysis ( 
, then 
) furnishes propanone and ethanal in a 
ratio. When HCl is added to " A ", the major product " B " is obtained. Which structure corresponds to " B "?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Ozonolysis giving propanone + ethanal implies the alkene is 2 -methyl-2-butene.
( 
) because each C of 
becomes the carbonyl of those fragments. Addition of HCl to an unsymmetrical alkene follows Markovnikov's rule (electrophilic addition): Cl goes to the more substituted 
2-chloro-2-methylbutane, structure .
