Answer

In this reaction, the reagent which we will use is 1.OsO42.NMO:

Step by step solution

01

Cyclopentene

It is a five-membered cyclic ring containing one double bond. Its chemical formula is C5H8. Its odor is petrol, and it is a colorless compound. It lies in the category of cycloalkene, and it contains an endocyclic (these bonds are present inside the cyclic ring) double bond.

02

Reagent used for the reaction

The double bond of a cyclic alkene can be oxidized to form vicinal diol with the help of two reagents first isKMnO4 in the cold basic solution, and the other one is osmium tetraoxide in the presence of NMO.

03

Reaction of cyclopentene

When we treat our reactant (cyclopentene) in the presence of osmium tetraoxide and NMO, the yield of the product will be higher than that of potassium permanganate.

Hence, the reagent for the above reaction is 1.OsO42.NMO:

Most popular questions from this chapter

When a single alkene monomer, such as ethylene, is polymerized, the product is a homopolymer. If a mixture of two alkene monomers is polymerized, however, a copolymer often results. The following structure represents a segment of a copolymer called Saran. What two monomers were copolymerized to make Saran?

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

Write the reactions.

What products are formed from hydration of 4-methyl cyclopentane? What can you say about the relative amounts of the products?

Draw the structure of a hydrocarbon that absorbs 2 molar equivalents of H2 on catalytic hydrogenation and gives only butanedial on ozonolysis.

Butanedial

Hydroxylation of cis-2-butene with OsO4yields a different product than hydroxylation of trans-2-butene. Draw the structure, show the stereochemistry of each product, and explain the difference between them.
