theta is the optical rotation produced by sugar solution of concentration C and taken in a glass tube of length 0.2 m and radius r . Then the solution is transferred to another glass tube of length 0.3 m and radius r and the remaining space is filled with distilled water. The optical rotation produced by this solution is

In a polarimeler experiment theta is the angle of rotation produced by a given sugar solution filling the tube. Now the solution is transfered to another tube of twice the length, same diameter and remaining volume is filled with distilled water. Angle of rotation is

Specific rotation of sugar solution is 0.5 deg m^2 kg^-1 * 200 kg m^-3 of impure sugar solution is taken in a sample polarimeter tube of length 20 cm and optical rotation is found to be 19^@ . The percentage of purity of sugar is

Light passes successively through two polarimeter tubes each of length 0.29 m. The first tube contains dextro-rotatory solution of concentration 60 kg m^-3 and specific rotation 0.01 rad m^2 kg^-1 . The second tube contains laevo-rotatory solution of concentration 30 kg m^-3 and specific rotation 0.02 rad m^2 kg^-1 . The net rotation produced is

(R)-3-bromocyclopentene (shown below) reacts with Br_2//C Cl_4 to form two products, Y and Z, Y is not optically active (does not rotate plane-polarized light). What is the structure of Y?

A Plano-convex lens of radius of curvature 0.1m is kept over a plane glass plate with curved surface of the lens touching it. The gap between the glass plate and the curved surface of the lens is filled with a liquid. If the combined focal length of the combination is 0.4m, calculate the refractive index of the material of the liquid. Given R.I. of the material of the lens is 1.5.
