Problem IV The Elimination reaction allows the removal from a molecule of a Leaving group and a neighboring Hydrogen to generate a double bond. When that reaction is performed on a cyclohexane, the leaving group (or in the example below, and the must be Axial as shown below. When the reaction is performed on the two molecule below (A and B), it is found that the reaction works very well on molecule A...

Can someone please help with these two questions? Thank you.
4. Here is an RNA transcript freshly transcribed from a gene. It is immature, meaning that it has not been processed yet into a mature mRNA. a) If you could zoom in on this molecule, what two things would you observe at the molecular level that would indicate to you that it is RNA and not DNA? b) Which end of the molecule was the last bit to be transcribed,...

need help with 14-21
Stereochemistry of the Su2 reaction In the Sn2 reaction the tetrahedral carbon center is inverted. We describe the mechanism as nudeophilic (Nuc) back side attack; the leaving group (LG) is leav ing from the front side. Generally, the LG and the Nucare electron rich so it would be unfavorable for them to react from the same side (charge repuls ion). The geometry of the carbon at the transition state is trigonal planar. 14) Label the 2-bromobuta...

Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...
