What will be the major product in an addition reaction if a substituted alkene has same number of hydrogens in both carbons of the double bond and different groups attached to them?
For example, What will be the major product of the addition reaction between 1-chloroprop-1-ene and hydrogen bromide?
$$\ce{CHCl=CH-CH3 + HBr -> ?}$$
And what will be the major product of the addition reaction between 1-bromo-2-chloroethen and hydrogen bromide?
$$\ce{CHBr=CHCl + HBr -> ?}$$
Can Markovnikov rule help us in this regard?
