Not necessarily , the meso form is optically inactive.
No, it is not optically active.
Allenes are optically active.
Yes
No. There are no Carbon atoms in propan-2-ol which have 4 different substituent groups attached and hence is not optically active.
Optically active
No, it is not optically active.
Allenes are optically active.
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.
Yes
An Optically active substance is one in which the carbon is bonded to 4 different groups i.e a chiral compound
Alanine is optically active because it has a chiral center, which is essential for a molecule to be 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.
CH2= CH - CHCl(Br) this structural isomer exists in two optically active 'd' and 'l' isomers.
Optically 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.
