Please need help on QUESTION 4
Show step by step in the synthesis of trans-2-butene from acetylene and an alkyl halide. Convert cis-3-hexene to trans-3-hexene. Calculate % yields of 1 -chloropropane and 2-chloroprpane from monochlorination of propane. Refer to the reaction, cyclohexene + NBS rightarrow 3-bromocyclohene, in Fig. 10-2 (p. 293). Write the propagation in three separate steps.

Can you show me the mechanism for 1-Butanol to Cis-2-Butene and
trans-2-butene?
(Does the carbocation shift from c1 to c2, then a hydride shift
from c2 to c1 (kicking off the water), then another water molecule
takes a hydrogen from c3, with the electrons then going from c3, to
share between c3 and c2?)
Many carbocation rearrangements involve hydride shifts (Section can also migrate to a positively charged carbon. in the direction that leads to a more stable carbocation. 5.12)...

I need some help with an alkene bromination lab. These are the directions: For this assignment, the target compound that you should synthesize is anti-2,3-dibromo-butane. This is a stereospecific electrophilic alkene addition reaction. Examine the product to determine the location of the new functionality. Keep in mind the bromonium ion intermediate and the consequences of its structure. The nucleophile again attacks in a manner that controls the stereochemistry of the product. ----------------------------- ***I need to know what materials, solvent, and...
