How many optical isomers are possible for glucose?
16 optical isomers
There are 16 optical isomers of glucose.
Which complex has optical isomers?
Octahedral complexes with six as their coordination number and three bidentate ligands will show optical isomerism because they do not show any kind of symmetry and they are non-superimposable mirror images of each other.
What is optical isomerism in complex compounds?
Optical isomerism occurs when a molecule is not superimposable with its mirror image. Structural isomers have the same chemical composition but the bonds are different.
Does EDTA show optical isomerism?
[Fe(EDTA)]- exhibits optical isomerism. In this complex, the number of rings formed are. Correct answer is ‘5’.
Why glucose has 16 optical isomers?
Thus, in glucose, carbon 2, 3, 4 and 5 are chiral centres and carbon 1 and 6 are achiral. Now, the formula to obtain the maximum number of possible optical isomers is 2n, where n is the total number of chiral centres. Since, glucose has four chiral centres, n=4 and we get, 24=16 optical isomers.
How do you find the glucose optical isomer?
We see that carbon atoms 2, 3, 4, and 5 are chiral centres. The maximum number of optical isomers is 2n , where n is the number of chiral centres. In glucose, n=4 , so 24 = 16 possible isomers.
How do you find optical isomers?
– The number of optical isomers of a compound is determined by calculating the number of chiral centres in it. – The maximum number of optical isomers is given by the formula 2n−1, where n is the number of chiral centres. So, the correct answer is option B.
Which of the following complexes will display optical isomerism?
2,3,4-Trichloropentane can exhibit optical isomerism.
What are optical isomers?
Optical isomers are two compounds which contain the same number and kinds of atoms, and bonds (i.e., the connectivity between atoms is the same), and different spatial arrangements of the atoms, but which have non-superimposable mirror images. Each non-superimposable mirror image structure is called an enantiomer.
What is optical isomerism with example?
Optical isomers are compounds that are nonsuperimposable mirror images of each other. If the arrangement in space makes the two isomers nonsuperimposable mirror images of each other, we call them optical isomers or enantiomers. An example is the amino acid alanine.
Which of the following complex does not show geometrical isomerism?
Geometrical isomerism is not possible for the complexes with coordination number 2 and 3 and tetrahedral complexes with coordination number 4 because in this case, all the four positions are equivalent. Thus, amongst them, [Ni(CO4)] will not show geometrical isomerism.
Which of the following complexes will show geometrical isomerism?
Aquachlorobis (ethylenediamine) cobalt(II) chloride will show cis and trans isomerism.
