Concept Introduction:
London dispersion force also called an induced dipole-induced dipole attraction is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
Dipole-dipole interaction results when two dipolar molecules interact with each other through space, there occurs a partially negative charge of one of the polar molecules is attracted to the partially positive charge of the second polar molecule.
Ion-dipole interaction results of an electrostatic interaction between a charged ion and a molecule that has a dipole.
A hydrogen bonding is partially an electrostatic attraction between

- What are the functions and procedure of analysis of many volatile organic molecules by using Gas chromatographyarrow_forwardOne method for the quantitative determination of the concentration of constituents in a sample analyzed by gas chromatography is area normalization. Here, complete elution of all the sample constituents is necessary. The area of each peak is then measured and corrected for differences in detector response to the different eluates. This correction involves dividing the area by an empirically determined correction factor. The concentration of the analyte is found from the ratio of its corrected area to the total corrected area of all peaks. For a chromatogram containing three peaks, the relative areas were found to be 16.4, 45.2 and 30.2, in order of increasing retention time. Calculate the percentage of each compound if the relative detector responses were 0.60, 0.78 and 0.88, respectively.arrow_forwardOne method for quantitative determination of the concentration of constituents in a sample analyzed by gas chromatography is the area normalization method.

A. partition chromatography – solute equilibrates between the stationary liquid and the mobile phase B. affinity chromatography – solute binds to a molecule specific for the solute C. molecular exclusion chromatography – solute is separated based on size D. adsorption chromatography – solute is adsorbed into solid particles E. ion-exchange chromatography – solute ions of the opposite charge are attracted to the stationary phasearrow_forwardWhich properties would be ideal in selecting the compound to be used as a primary standard for quantitative volumetric analysis?arrow_forward
- The height of three peaks; A, B, and C obtained in a gas chromatogram are 20.6 mm, 17.5 mm and 40.6 mm. The width of the peaks, at half height, are 4.4 mm, 4.0 mm and 3.9 mm, respectively. Calculate the percentage composition of A in the sample.arrow_forwardin a chromatographic analysis of water from a drinking fountain gives area of 1.56*10^4, 5.12*10^4, 1.49*10^4 and 1.76*10^4 for CH3CL3, CHCL2BR, CHCLBR2 and CHBR3 respectively. determine the percentage concentration of each of the triichoromethane in the samplearrow_forwardA scientist wishes to measure the concentration of methyl benzoate in a plant stream by gas chromatography. He prepares a sample of butyl benzoate to use as an internal standard. The results of a preliminary run, which used a solution known to contain 1.37 mg/mL of methyl benzoate (peak A) and 1.51 mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 3.40×102 and the area of peak B is determined to be 398 measured in arbitrary units by the computer. To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.49 mg/mL is mixed with 1.00 mL of the plant stream material. Analysis of the mixture gave a peak area of 437 for peak A and 415 for peak B. What is the concentration of methyl benzoate in the plant stream?arrow_forward
