How many sigma bonds were formed from how many pi bonds in the diels-alder reaction lab? (5pts) did your test tube heat up after you added the cyclopentadiene to the dissolved maleic anhydride (ethyl acetate and hexane were the solvents)? why or why not would the test tube be hot, explain in detail? (15 pts) the diel-alder reaction is said to be "stereospecific." what does that mean in terms of product produced in the diels- alder lab? (15 pts) 5. what is an example of an aldol reaction? (10 pts)

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.
