Consider the following errors that could be made when running TLC. Indicate what should be done to correct the error. a. A two-component mixture containing 1-octene and 1, 4-dimethylbenzene gave only one spot with an Rf value of 0.95. The solvent used was acetone.

Please see explanation column for answer.

Explanation:  For A two-component mixture containing 1-octene and 1, 4-dimethylbenzene with acetone.

Error  The retention factor (Rf) is 0.95 and the two spots are coming simultaneously together producing only one spot indicating that that the choice of  solvent we have used is too polar.  The compounds are interacting rapidly  with the very polar  solvent and have very  low interaction with the stationary phase. than the mobile phase.

Solution:, We will need to try other low polar solvent that can allow two spots to be formed on the TLC plate eg is the use of  different percentage s of hexane in ethyl acetate  ether 10% or 20%.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
