Interpretation:
The following questions regarding 1,3,5-cycloheptatriene are to be answered:
a) How many p atomic orbitals are present in 1,3,5-cycloheptatriene. b) How many molecular orbitals describe this conjugated system. c) How many are bonding molecular orbitals. d) How many are anti-bonding molecular orbitals e) Which molecular orbitals are filled with electrons. f) If this molecule absorbs a photon of UV light, between which two molecular orbitals the electron will move.
Concept introduction:
When atomic orbitals overlap among themselves equal number of molecular orbitals, bonding and anti-bonding, are produced. Electrons occupy the molecular orbitals following Auf bau, Pauli’s exclusion principle and Hund’s rule. When the molecule absorbs a photon of UV light, the electron will move from the highest occupied molecular orbital (HOMO) to lowest unoccupied molecular orbital (LUMO).

- Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…arrow_forwardNonearrow_forwardHow will you prepare the following buffers? 2.5 L of 1.5M buffer, pH = 10.5 from NH4Cl and NH3arrow_forward
