For each of the following pairs of compounds, choose which will elute faster in a TLC experiment (i. e., which compound will have a larger Rf value). Explain what factors led to your choice. 6 pt a. Naphthalene or 1-Bromonaphthalene Choice Explanation: 1-Bromonaphthalene is more polar than Naphthalene. If polarity is higher, its Rf value will be less which means that molecule will travel less distance (lower Rf value) during a TLC experiment.

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
