The given compound has only one asymmetric center but reason for four stereoisomers has to be explained. Concept introduction: Stereoisomers are isomers which have different spatial arrangement in spite of same bond connectivity. Stereoisomers are due to the presence of stereocenter. Stereocenter may be an atom axis (bond) or plane from which interchanging of two groups leads to stereoisomers. Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups. The equation for finding Stereoisomers from number of asymmetric centers in compounds is 2 n , in which ‘n’ is the number of asymmetric centers. If the four groups attached to a double bond are different, then interchanging of groups of double bond (left side or right side) will lead to cis-trans isomers (stereoisomers).

Interpretation Introduction

Interpretation:

The given compound has only one asymmetric center but reason for four stereoisomers has to be explained.

Concept introduction:

Stereoisomers are isomers which have different spatial arrangement in spite of same bond connectivity. Stereoisomers are due to the presence of stereocenter. Stereocenter may be an atom axis (bond) or plane from which interchanging of two groups leads to stereoisomers.

Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.

The equation for finding Stereoisomers from number of asymmetric centers in compounds is 2n, in which ‘n’ is the number of asymmetric centers.

If the four groups attached to a double bond are different, then interchanging of groups of double bond (left side or right side) will lead to cis-trans isomers (stereoisomers).

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. • If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T G OH де OH This transformation can't be done in one step.
