A is correct but R is not correct
A is not correct but R is correct
D.
A is not correct but R is correct
According to Markownikoff's rule, the addition of reagents such as HX, H2O and HOX with unsymmetrical alkanes occurs in such a way that the negative part of the adding molecule goes to that carbon atom of the double bond which carries lesser number of hydrogen atoms.
