Question

Addition of \[{{\mathbf{O}}_{\mathbf{s}}}{{\mathbf{O}}_{\mathbf{4}}}\]to cyclopentene would give a product which is
A. achiral
B. racemic
C. meso
D. optically active

Answer 1

Hint: in the given question the reaction of cyclopentene is discussed under the addition of a compound osmium tetroxide which is a liquid. Cyclopentene seems to be a colorless liquid which might be Less dense than water and is insoluble in water.

Complete Step by step answer: Osmium tetroxide, the chemical formula \[\left( {{O_s}{O_4}} \right)\]is an unstable liquid which is most useful for the synthesis of \[1,2\]diols from alkenes. Cyclopentene a chemical compound which have a formula\[{\left( {C{H_2}} \right)_3}{\left( {CH} \right)_2}\] and is a colorless liquid having a petrol-like odor, in specific.
Moreover, we can say that meso compounds are achiral compounds that contain multiple number of chiral centers. So, is superimposed on its mirror image and is optically inactive in spite of its stereocenters. a meso compound would have two or more stereocenters, and also an internal plane within. By the presence of these properties we can easily recognize the meso compounds.
In the given reaction osmium tetroxide \[\left( {{O_s}{O_4}} \right)\]​ is the reagent used to form the product which is diols in presence of water that is \[{H_2}O/{H^ + }\].the \[\left( {{O_s}{O_4}} \right)\]​ is a reaction of the syn addition of diols.

When cyclopentene reacts with osmium tetroxide it results in yield of a meso compound.

Hence, the correct option is C.

Note: cyclopentene is moreover Used in making rubber and plastics goods. Cyclopentene is used in analyzing the mechanisms of various organic reactions. It has a vast use in forming a component of gasoline. Also, it is produced industrially in huge amounts using steam cracking of naphtha.
