The mechanism for the preparation of ketone from nitrile using Grignard reagent has to be given. Concept introduction: Grignard reagent: It is an organometallic compound that contains carbon magnesium bond. The electronegativity difference between carbon and magnesium makes the bond more polar. Grignard reagent useful in the synthesis of a desired organic compound that is not easily synthesis by other methods. The grignardreagent can be synthesis by the reaction between magnesium turning with an organic halide with the desired group. The Grignard reagent can act as a nucleophile and undergoes nucleophilic reactions. Grignard reagent on reacting with nitriles gives a ketone. This reaction can be shown as:

An expression for the root mean square velocity, vrms, of a gas was derived. Using Maxwell’s velocity distribution, one can also calculate the mean velocity and the most probable velocity (mp) of a collection of molecules. The equations used for these two quantities are vmean=(8RT/πM)1/2 and vmp=(2RT/M)1/2 These values have a fixed relationship to each other.(a) Arrange these three quantities in order of increasing magnitude.(b) Show that the relative magnitudes are independent of the molar mass of the gas.(c) Use the smallest velocity as a reference for establishing the order of magnitude and determine the relationship between the larger and smaller values.

The reaction of solid dimethylhydrazine, (CH3)2N2H2, and liquefied dinitrogen tetroxide, N2O4, has been investigated for use as rocket fuel. The reaction produces the gases carbon dioxide (CO2), nitrogen (N2), and water vapor (H2O), which are ejected in the exhaust gases. In a controlled experiment, solid dimethylhydrazine was reacted with excess dinitrogen tetroxide, and the gases were collected in a closed balloon until a pressure of 2.50 atm and a temperature of 400.0 K were reached.(a) What are the partial pressures of CO2, N2, and H2O?(b) When the CO2 is removed by chemical reaction, what are the partial pressures of the remaining gases?
