Concept introduction: Rubber is a polymer (long chain molecules) made from organic compound isoprene. The molecules in rubber are arranged in a tangled up position than an aligned position and due to thermal motion they lose their alignment and go back to their tangled state and this is called an elastic contact caused by an entropic force.
To determine: The stretching is an exothermic or endothermic process.

That is, there Ar must now be a new molecule present with at least one C - OH bond. In the drawing area below, show the detailed mechanism that could convert the molecule above into the new molecule. $ Add/Remove steparrow_forwardSo the thing is im trying to memorize VESPR Shapes in order to be able to solve problems like so, and I need help with making circles like the second image that's in blue or using an x and y axis plane in order to memorize these and be able to solve those type of problems. Especially like the ones given in the top / first image. (180 , 120 , 109.5) Can you help me with this.arrow_forward

The growth and production of cells, called cell proliferation, is known to involve an enzyme called protein farnesyltransferase (PFTase). It is thought that inhibitors pf PFTase may be useful as anticancer drugs. The following molecule showed moderate activity as a potential PFTase inhibitor. Draw all stereoisomers of this compound.
