Consider the reaction of 2 -Butanol given below
The relation between the major product (P) and (Q) formed above is
Chain isomers
Positional isomers
Functional isomers
Geometrical isomers
Al2O3, causes Saytzeff's elimination.
While ThO2, causes Hoffman's elimination.
We can see that (P) and (Q) are positional isomers as the position of the double bond is shifted
Hence, the correct answer is option (2)
