Which among the following defines Meso forms of isomers?a)Meso form is...
Meso forms of isomers are single compounds and their molecules are achiral hence they cannot be separated into pairs.


Additional Information: A meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active. This means that despite containing two or more stereogenic centers, the molecule is not chiral.

Meso forms of isomers

Meso forms of isomers are a special type of stereoisomers that exhibit unique properties. The correct answer to the question is option 'D', which states that meso forms of isomers are a single compound. Let us understand this in detail.

Definition:

Meso forms of isomers are stereoisomers that possess an internal plane of symmetry. Due to this symmetry element, the molecule appears to be optically inactive, but it is a single compound, unlike other stereoisomers, which exist as a pair of enantiomers.

Properties:

1. Internal plane of symmetry:

Meso forms of isomers possess an internal plane of symmetry, which divides the molecule into two identical halves. Due to this symmetry element, the molecule appears to be achiral or optically inactive.

2. No enantiomeric pairs:

Unlike other stereoisomers, meso forms of isomers do not exist as a pair of enantiomers. They are a single compound that possesses an internal plane of symmetry.

3. Chirality:

The molecules of meso isomers are chiral, but the presence of an internal plane of symmetry cancels out the effect of chirality, making the molecule optically inactive.

4. Separation:

Meso isomers can be separated into optically active enantiomeric pairs by breaking the internal plane of symmetry. This can be achieved by introducing a chiral center in the molecule or by inducing a chemical reaction that breaks the symmetry element.

Conclusion:

Meso forms of isomers are a unique type of stereoisomers that possess an internal plane of symmetry, making them appear optically inactive. However, they are a single compound and exhibit chirality. They can be separated into optically active enantiomeric pairs by breaking the internal plane of symmetry.

Similar Class 11 Doubts

Attempt All sub parts from each question.Molecular Perspective In water, there are two types of molecules. Some molecules are at the surface, called exterior molecules, and some molecules are inside, called interior molecules. The interior molecules are attracted to all the molecules around them. The exterior molecules are attracted to only the other surface molecules and to those below the surface. So that the energy state of the molecules on the interior is much lower than that of the molecules on the exterior. The molecules always try to maintain a lower energy state and hence the exterior molecules experience a downward force. This force is known as cohesive force. As a result they try to maintain a minimum surface area, thus allowing more molecules to have a lower energy state. Thus surface tension is created. The water molecules attract one another due to the water molecule’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen, cause water to "stick " together. This is why there is surface tension. Water has very high surface tension. It is 72.8 milli newton per meter at 20°C.Q. Which one of the following is the correct molecular structure of water molecule?
