Re: Tata Institute Of Fundamental Research GS

Ya sure I will get the Tata Institute Of Fundamental Research, Graduate School Chemistry exam paper so that you can prepare.

Here is the exam paper
A quantum mechanical state Q is a superposition of two normalized energy eigenstates A and B in an amplitude ratio 2:1. If the two states are degenerate with a common eigenvalue E, what is the energy of the state Q?
A) 0,
B) 3E
C) 5E
D) E

For the above, if the states were non-degenerate and with energy eigenvalues E and −E respectively, then what would be the expectation value of the energy?
A) 3E
B) 5E
C) E
D) None of the above

Suppose we inscribe a circle inside an equilateral triangle, and then inscribe a square inside this circle. What is the ratio of the side of the square to the side of the triangle?
A) 1: 3
B) 2:5
C) 1: 6
D) 1:2

The reaction of sodium ethoxide with ethyliodide to form diethyl ether is termed
A) electrophilic substitution
B) nucleophilic substitution
C) electrophilic addition
D) radical substitution

Consider a container of volume 5.0 L that is divided into two compartments of equal size. In the left compartment there is nitrogen at 1.0 atm and 25 °C; in the right compartment there is hydrogen at the same temperature and pressure. What will happen when the partition is removed?
A) The entropy increases, and the free energy decreases.
B) The entropy decreases, and the free energy decreases.
C) The entropy increases, and the free energy increases.
D) The entropy decreases, and the free energy increases.
