Question

Which one has the highest vibrational frequency among the single, double and triple C-C bonds? Single bond Double bond Triple bond Undetermined The wavefunction for the ground state of a harmonic oscillator is psi_0 = (alpha/pi)^1/4 e^-ax^2/2 middot The is, integral^+infinity_-infinity psi*_0 (-ih d/dx) psi_0 dx = h integral^+infinity_-infinity psi*_0 (-ih d/dx) psi_0 dx = 0 integral^+infinity_-infinity psi*_0 psi_0 dx = 1 integral^+infinity_-infinity psi*_0 psi_0 dx = 0 Y^2_2 (theta, phi) and Y^2_-2 (theta, phi) are two spherical harmonics. Which of the following is FALSE? integral^pi_0 sin theta d theta integral^2 pi_0 (Y^2_2)*Y^2_-2 d phi = 0 integral^pi_0 sin theta d theta integral^2 pi_0 (Y^2_2)*Y^2_-2 d phi = 1 integral^pi_0 sin theta d theta integral^2 pi_0 (Y^2_-2)*Y^2_-2 d phi = 1 integral^pi_0 sin theta d theta integral^2 pi_0 (Y^2_2)*Y^2_2 d phi = 1 What is atomic orbital of the H-atom? Bohr radius radial distribution function total wavefunction radial wafefunction Which of the following statement is False? The energy of the H-atom depends on the principle quantum number and a few physical constants. The angular momentum has the same unit as Planck constant. The angular momentum is quantized and independent of mass of particle. Since only the z-component of angular momentum could be simultaneously determined for the given state, L_x and L_y do not exist quantum mechanically. C_60 can be approximated as a sphere, and the electrons can be thought of as being confined to the surface of the sphere. What is the total angular momentum of an electron in the l = 3 states? 2 Squareroot 3 h 3 h 2 Squareroot 5 h Squareroot 6 h The average value of the total angular momentum for 3p orbital for the hydrogen atom is 4h^2 2h^2 Squareroot 2h h^2

Explanation / Answer

8) vibrational frequency is directly proportional to the bond strength or force constant i.e.- stronger is the bond more becomes the vibration frequency and vice versa. Since bond strength of triple bond is more than that of double which in turn is more than single bond, triple bond has highest vibrational frequency.
