Chapter 7 - How to Conduct Pretesting. The systematic checking or pretesting of a questionnaire is central to planning a good survey. As mentioned earlier in this series, the survey sponsors should play a major role in developing the data-collection instruments being proposed-including any testing being done.
Question and answer. The simplest unsaturated hydrocarbon is methane, a one-carbon molecule. Please select the best answer from the choices provided T F. The simplest unsaturated hydrocarbon is methane, a one-carbon molecule.This is false. mixture is different from a compound because each substance in a mixture a. retains its own properties. c. forms an ion. b. changes its electric charge. d. changes from a solid to a liquid.
â¢ In saturated hydrocarbons, all the bonds are single bonds. In unsaturated hydrocarbons, double bonds and triple bonds are also present. â¢ Saturated hydrocarbons have the highest number of hydrogen atoms, carbon atoms can accommodate in contrast to unsaturated hydrocarbons.â¢ Saturated hydrocarbons are the simplest type of hydrocarbons.n unsaturated hydrocarbons, there are double or triple bonds between the carbon atoms. Since there are multiple bonds, the optimal number of hydrogen atoms is not there in the molecule. Alkenes and alkynes are examples for unsaturated hydrocarbons.
