 3.   2-phenylpropene on acidic hydration gives

(a) 2-phenyl-2-propanol (b) 2-phenyl-1-propanol  

(c) 3-phenyl-1-propanol (d) 1-phenyl-2-propanol

Answer : (a)

Answer explanation: Organic chemistry is based on living compounds, molecules,atoms and ions .Chemicals can be classified as Inorganic or Organic .Inorganic is non-living structures of chemicals while organic are living compounds or singular molecular structures. 

Now Propene is CH3=CH2-CH3 ( Here '=' indicates double bond ; this means propene is jointly connected through methyl group (CH3) and Benzyl group (C6H5-CH2)

Now as shown above, CH3=CH2 can be written as C2H5 which is four carbon short of benzyl group (C6H6 is Benzene).Here we can see that CH3=CH2 is a covalent bond and non-ionic in nature .Hence ionisation can happen only on right,CH3 side of the above compound.

Hence hydration through acidic solution (which is acidic hydration) happens only on right side of the chemical structure ,that is CH3. Hence CH3 becomes CH2-OH ,which is hydroxyl group added to the CH3 replacing one hydrogen ion in the outer 's' orbit  (s,p,d,f are the orbit shapes)

The following chart explains the organic chemistry configuration types in the right perspective 

Thus the above chart shows the difference between different types of ions , atoms,molecules ,compounds and atomic particles of lower order in the Periodic predecession of Chemicals 

Now let us consider a totally different scenario,which has all of the above types of chemical structures .This is known as Markonikov's rule ,which states that bonds,molecules,ions and compounds can be added or substracted from a chemical under reaction with another chemical( under right conditions),which results in complete new arrangement of the atomic structure inside the molecule ,whose valence electrons flyoff from one chemical and adds to another due to electro magnetic attraction between these two. 

 ((  In Nuclear science, this activity is done using an instrument called 'Cyclotron' which when rotated at great speed makes the atom lose one electron and change into another chemical ( which is called radio isotopy) This has been used in Alchemy for metal transformation . Thus deeper study of Organic chemistry leads to Alchemical insights as described above.  ))
