Isomerism and Stereochemistry Worksheet
Isomerism and Stereochemistry Worksheet Compounds which differ in their properties and structural formula but have same molecular formula are called isomers and this phenomenon is called isomerism. Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms within molecules. An important branch of stereochemistry is the study of chiral molecules. Here, you can find some questions related to “Isomerism and Stereochemistry” and their answers: 1. Which pair represents chain...

Conformation Worksheet These are formed by rotation around C – C bond. Maximum number of conformation for an alkane is infinite. Conformers differ slightly in energy. After 360 rotations conformation is back. Main structural work was made by Sawhorse and Newmann. Conformers have a slight difference in energy. Conformers cannot be separated. In staggered conformation the angle between H – C – H is 60° while in eclipsed it is less than 10°. Here, you can find some questions related to “Conformation” and their answers: 1....

E, Z, D, L and R, S configurations Worksheet E = Entigegen means same priorities are on opposite side like trans. Z = Zussaman [means together] i.e., same priorities are on same side like cis. R and S configurations was introduced by Cohn, Ingold and Prelog. Here R means Rectus (means clock-wise rotation) and S means Sinistere (means antilock-wise rotation). Here, you can find some questions related to “E, Z, D, L and R, S configurations” and their answers: 1. The ‘E’-isomer is: 2. (a) E,...

Diastereromer Worksheet It is a stereoisomer of a compound having two or more chiral centers that is not a mirror image of another stereoisomer of the same compound. Here, you can find some questions related to “Diastereromer, Meso compound and Racemic mixture” and their answers: 1. The stereoisomers which are neither superimposable nor mirror image are called: (a) meso compound (b) enanitiomers (c) diastereomers (d) racemic mixture 2. In which of the following separation methods only one enantiomer is recovered...

Optical isomerism Worksheet It is the type of isomerism in which the compounds having same molecular formula differ in their direction of bringing the optical rotation or the extent of bringing the optical rotation i.e., different rotation of plane polarized light. Here, you can find some questions related to “Optical isomerism” and their answers: 1. Which of the following compounds exhibits stereo isomerism? (a) 2-methyl-1-butene (b) 3-methyl butyne (c) 2-methyl butanoic acid (d) 3-methyl butanoic...

Geometric Isomers Worksheet It is the type of isomerism in which the compounds possessing same molecular formula differ in their properties due to the difference in their geometry, i.e., due to the difference in the direction of attachment of same atoms or groups in their molecule. It is not shown by single bonded compounds like (C—C) due to free rotation. It is shown by [>C = C<], [>C = N-], [-N = N-], cyclo alkanes. Here, you can find some questions related to “Geometric Isomers” and their answers: 1. Geometrical...

Structural isomerism worksheet In this type of isomerism compounds molecular formula differ in their properties due to the difference in the linkage of atoms inside the molecule, i.e., due to the difference in their structure. Here isomers differs in the connectivity of carbon atoms, i.e., differ is structural formula. Here, you can find some questions related to “Structural isomerism ” and their answers: 1. The isomerism, which differs only in the arrangement of atoms or groups within the molecule without any reference to the...
