Concept Introduction:
Valence shell electron pair repulsion theory (VSEPR) predicts shape of molecules with use of arrangement of electrons around central metal atom. Its postulates are as follows:
1. The shape of molecules is governed by repulsion between electron pairs situated in the outermost or valence shell of the atoms.
2. A distortion is observed in the shape of the molecules if lone pairs are present in it. These are electron pairs that do not participate in the
3. The order of repulsion of electron pairs is as follows:
4. Multiple bonds create more repulsion as compared to single bonds.
5. The following table shows various molecular shapes that match different number of electron pairs:
The geometry of the molecule is predicted with help of the steric number. The formula to calculate steric number is as follows:
Bond angle is angle that exists between two bonded electron pairs or simply between two bonds. It is the angle that is formed between three atoms with atleast two bonds. It is a major contributor to shape of molecule and is helpful to predict the difference between various geometries of molecules.

- Lin and Brown described a quantitative method for methanol based on its effect on the visible spectrum of methylene blue. In the absence of methanol, methylene blue has two prominent absorption bands at 610 nm and 663 nm, which correspond to the monomer and the dimer, respectively. In the presence of methanol, the intensity of the dimer’s absorption band decreases, while that for the monomer increases. For concentrations of methanol between 0 and 30% v/v, the ratio of the two absorbance, A663/ A610, is a linear function of the amount of methanol. Use the following standardization data to determine the %v/v methanol in a sample if A610 is 0.75 and A663 is 1.07.arrow_forwardThe crystal field splitting energy, Δ, of a complex is determined to be 2.9 × 10-19 What wavelength of light would this complex absorb? What color of light is this? What color would the compound be in solution?arrow_forwardA key component of a monochromator is the exit slit. As the exit slit is narrowed, the bandwidth of light (i.e., the range of wavelengths) exiting the slit gets smaller, leading to higher resolution. What is a possible disadvantage of narrowing the exit slit? (Hint: why might a narrower slit lower the sensitivity of the measurement?).arrow_forward

If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... No reaction. Explanation Check O + G 1.
