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.
Methane consists of only a single carbon atom and four hydrogen atoms, each coupled with a single bond. It can be considered the simplest hydrocarbon because it has the absolu â¦ te minimum number of carbon and hydrogen atoms, and the simplest bond structure, of any hydrocarbon. 1 person found this useful.s ethene contains double bond it is considered as unsaturated hydrocarbon. Note-hydrocarbon is said to saturated when it contain C-C single bond and hydrocarbon is said to un â¦ saturated when it has carbon carbon double or triple bonds.
