When bromobenzene reacts with propene in a heck reaction (in the presence of pd(php3)4 and et3n) , two constitutional isomers ar
e obtained as the products. give the structures of the two products. interactive 3d display mode?
1 answer:
The Heck reaction is a coupling reaction that combines an unsaturated halide with an alkene in the presence of base and palladium catalyst to provide a substituted alkene. It an important reaction as it forms a carbon-carbon bond and allows substitution on sp² hybridized carbons.
In this example, we have bromobenzene reacting with propene and are told that two constitutional isomers are formed. The expected product is the first one shown which has the benzene substitute onto the terminal end of the alkene. The isomer by-product that is formed is substitution onto the central carbon of the propene which leads to a product with a terminal alkene.

Answer:
Horse latitude, trade winds
Explanation:
- The area of the low pressure or the calm consists of the variable light winds that blow near the equator are known to the marines as the doldrums and they form a circuital pattern near the earth atmosphere.
- Forms at a center of the near the higher pressure systems called as the horse latitudes where the trade winds at the surface are weak and variable and this zone is found generally in latitudes of the 30° North and South of the equator and move in an east to west direction.
