Chapter 8: Q70aE. (page 262)

We’ll see in the next chapter that alkynes undergo many of the same reactions that alkenes do. What product might you expect from each of the following reactions?

Short Answer

Expert verified

The reaction is an example of electrophilic addition. A brominium ion is formed when alkyne undergoes elecrophilic addition reaction.

Step by step solution

02

Chemical reaction involved

03

Reaction of alkyne with halide

When alkyne reacts with halide, they undergo an additional reaction to form halogen substituted alkene. Alkyne followsMarkovnikovregiochemistry in which two added halogen atoms are always in a trans relationship with each other.

What products would you obtain from catalytic hydrogenation of the following alkenes?

The following cycloalkene gives a mixture of two alcohols on hydroboration followed by oxidation. Draw the structure of both, and explain the result.

Compound A has the formula C10H16. On catalytic hydrogenation over palladium, it reacts with only 1 molar equivalent of H2. Compound A also undergoes reaction with ozone, followed by zinc treatment, to yield a symmetrical diketone, B(C10H16O2).

How many rings does A have?
