Out of C6H5CH2Cl and C6H5CHClC6H5, which is more easily hydrolyzed by aqueous KOH.


Hydrolysis by aqueous KOH proceeds through the formation of carbonation. If carbocation is stable, then the compound is easily hydrolyzed by aqueous KOH. Now,C6H5CH2CL forms 1°-carbocation, while C6H5CHCLC6H5 forms 2°-carbocation, which is more stable than 1°-carbocation.Hence,C6H5CHCLC6H5 is hydrolyzed more easily than C6H5CH2CL by aqueous KOH.
Give two differences between N1 and N2 reactions.
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
