The reason for hydroxyl − O H group at third Carbon is more acidic than that of the second Carbon in v i t a m i n C is has be explained. Concept Introduction: Acidity is defined as the property to accept electrons or tendency to donate hydrogen ion from the molecule. Compounds having higher tendency to donate hydrogen ion is more acidic than the compounds having less tendency to donate hydrogen ion. Electronegativity i s a measure of the tendency of an atom to attract a bonding pair of electrons. Electronegative of hybrid orbitals depends upon the % s character. Hence more the s character more the electronegativity. The acidity depends upon the electronegativity of an atom. More the electronegativity more the acidity.

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?
