What is meant by hydroboration-oxidation reaction?Illustrate it with an example.
The addition of borane followed by oxidation is known as the hydroboration-oxidation reaction. For example,propan-1-ol is produced by the hydroboration-oxidation reaction of propene. In this reaction, propene reacts with diborane(BH3)2 to form trialkyl borane as an additional product.This additional product is oxidized to alcohol by hydrogen peroxide in the presence of aqueous sodium hydroxide

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 \(P,O,Q\).
