Question
Chapter 8, Problem 8.90PAE
Interpretation Introduction
Interpretation:
A short summary should be written to explain how researches over Geckos have resulted into adhesive designing.
Concept introduction:
Geckos have capacity to climb smooth vertical walls through the tips of its tiny hair like setae in its feet.
As per the researches, this climbing occurs due to the Van der waal’s forces between the setae of its feet and the surface of the walls.
The researches are done to create such adhesive or tapes which could mimic this behavior.

- Which carbocation is more stable?arrow_forwardAre the products of the given reaction correct? Why or why not?arrow_forwardThe question below asks why the products shown are NOT the correct products. I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates"). In other words, why is HCl added to the terminal alkene rather than the internal alkene?arrow_forward
