Q.
What is the major product expected from the following reaction ?
Where is an isotope of Hydrogen

Solution:
Formation of above species is more favourable. The stability order of carbocations is
Now, carbocation formed is hybridised that is triangular planar as shown below
Either the attack from above or below formation of the plane of the molecule, so there is probability of resultant product as shown below i.e., both product will form
