Hello everyone, let's look at the question.
00:02
Now in this question we have given a reaction where an alken, exocyclic alken is reacting with hbr giving product a or product b.
00:12
So we have to find out which product is the major product and we have given some questions about this reaction.
00:20
So here first i will write the reaction.
00:24
So now this exocyclic double bond is reacting with hbr.
00:29
Right so it is an electrophilic what addition reaction right and see it follows mark onikov's rule so we should use mark onikov's rule to identify the major product so i will write both the product so here the product one is a product a is this one so this is product a and product b is it is given as or right so this is the product b right see the first question is which product a or b would be the major product.

See here, if we use a markornikov's rule, see markov's rule says that in case of an electrophilic addition reaction of an unsymmetrical alken, the proton will add to the carbon having more hydrogen atom, and this nucleophile will add to the carbon having less number of hydrogen atom.

If i consider here, this carbon is attached with two hydrogen, and here there is no hydrogen...
