Alanine is optically active because it has a chiral center, which is essential for a molecule to be optically active.

∙ 13y agoyes b/c each each enantiomer will rotate light a different way...aka clockwise and counterclockwise,,,how do i know? im studying 2nd year biochem

∙ 10y agoNo. Glycine is achiral and is not optically active.

How can you identify is the substance is optically active?
An Optically active substance is one in which the carbon is bonded to 4 different groups i.e a chiral compound
Which noncyclic isomers of bromochloropropene are optically active?
CH2= CH - CHCl(Br) this structural isomer exists in two optically active 'd' and 'l' isomers.
How do you distiguish for the optically active and in active?
First of all we should know what optically active molecules are "Those molecules which possess asymmetric(chiral) carbon atoms have the ability to rotate the plane polarized light(light of one wavelength having its electrical character vibrating in one direction only) to the left or to the right are known as Optically active molecules" while those molecules not following the former scenario are known as Optically Inactive molecules. All in all molecules having asymmetric carbon atoms are known as optically active molecules for example glucose(rotate plane polarized light to the left) & fructose(rotate plane polarized light to the right) are optically active molecules. While molecules lacking asymmetric carbon atoms are optically inactive molecules for example water is optically inactive. And that's how we can distinguish between these two molecular classifications.
What is the difference between racemic mixture and mesocompounds?
1:1 molar solution of two enantiomers is recemic mixture and it may be resolved into two parts by chemical means while mesoform is a pure substance and can not be resolved, but both these are optically inactive.
How many isomers can be obtained from C6H14?
None, as it has 5 structural isomers in which none of are optically active.
Is phenylmethanol optically active?
No, it is not optically active.
What is A mixture of equal amounts of two enantiomers?
its called a racemic mixture and is optically inactive
Is allene optically active or not?
Allenes are optically active.
What is difference between a racemic mixture and a meso compound?
Both are optically inactive, but for different reasons. A racemic mixture contains chiral molecules that, individually, are optically active. But the mixture contains optically active enantiomers, which essentially cancel out each other's optical activity (one enantiomer rotates light one way, the other rotates it back). A meso compound, however, is optically inactive on its own. It can have chiral centers within its structure, but due to symmetry it will still be optically inactive.
What is asymmetrical symmetry?
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.
Are diastereomers optically active?
Not necessarily , the meso form is optically inactive.
How is chiral resolution process?
The separation of a racemic mixture into two optically active forms (+ or −) is known as chiral resolution. Since diastereomers have different chemical and physical properties, they can be separated into corresponding enantiomers by chiral resolution. This method is called enantiomeric enrichment, and it is a process of continuously increasing the percentage of enantiomers until the enantiomeric excess finally approaches 100%./BOC Sciences
Is lactose optically active?
Yes
How can you identify is the substance is optically active?

Is propan-2-ol is optically active?
No. There are no Carbon atoms in propan-2-ol which have 4 different substituent groups attached and hence is not optically active.
Which noncyclic isomers of bromochloropropene are optically active?
CH2= CH - CHCl(Br) this structural isomer exists in two optically active 'd' and 'l' isomers.
Optical isomerism in aldehydes and ketones?
The carbonyl group present in aldehydes or ketones itself is optically inactive but if a carbon attached to carbonyl group is asymmetric (attached to four different groups or atoms) then such compound may show to enantiomers as there are two enantiomers of CH3-CHCl-CHO.
