These are not optical isomers they are functional group isomers a subcategory of structural isomers.

CH3CH2COOH and CH3CHOHCHO have chiral centers, which are carbon atoms bonded to four distinct groups. Their mirror images are non-superimposable. This asymmetry results in optical isomerism, where the molecules exist as enantiomers.

How does one recognize optical isomers?

Optical isomers are isomers of molecules which are non-superimposible. They have a left hand and a right hand and this is how you distinguish between them.


Which is a structural isomer of ch3ch2cooh that has a lower boiling point a ch3ch2cooch3 b ch3cooch3 c ch3coch2oh d hochchoch3 e ch3chohcho?

The structural isomer of CH3CH2COOH with a lower boiling point is CH3COOCH3 (option B). This is because esters typically have lower boiling points compared to carboxylic acids due to weaker intermolecular forces.


What is the difference between optical isomer and optically active isomer?

Optical isomers are molecules that are mirror images of each other and are non-superimposable. Optically active isomers are molecules that rotate the plane of polarized light. All optical isomers are optically active, but not all optically active isomers are optical isomers.

What is the difference between d ascorbic and L ascorbic acid?

l ascorbic acid and d ascorbic acid are optical isomers of each other. Optical isomers have the same physical and chemical properties but bend the plane of polarisation of polarized light in different directions.It is also called ChiralitySee the related link for more info on optical isomers.


What is formula to find optical isomerism?

To determine the number of optical isomers of a compound, use the formula: 2^n, where n is the number of chiral centers in the molecule. Chiral centers are carbon atoms bonded to four distinct substituents. Each chiral center can give rise to two optical isomers due to their non-superimposable mirror images.

What are the optical isomers of d-fructose?

The optical isomers of D-fructose are D-fructose (also known as D-arabino-hexulose) and L-fructose (also known as L-sorbofuranose). These isomers differ in their spatial arrangement around a chiral carbon atom, leading to different optical properties.


What are compuonds withe the same cheimcial formule but different structure?

Isomers are compounds with the same chemical formula but different structures. They can have different physical and chemical properties due to their unique arrangement of atoms. Examples include structural isomers, geometric isomers, and optical isomers.


Why do some isomers lack optical activity?

Some isomers lack optical activity because they have a plane of symmetry or a center of symmetry that results in the molecule being superimposable on its mirror image. This makes them achiral and unable to rotate the plane of polarized light, thus lacking optical activity.
