Want this question answered?
An Optically active substance is one in which the carbon is bonded to 4 different groups i.e a chiral compound
Optical activity has no affect on the combustion of a material; therefore, there is no reason an optically active alcohol could not be used as a fuel.
Alanine is optically active because it has a chiral center, which is essential for a molecule to be optically active.
CH2= CH - CHCl(Br) this structural isomer exists in two optically active 'd' and 'l' isomers.
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.

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.
Not necessarily , the meso form is optically inactive.
touluene All Biphenyls and Allenes are optically active without a chiral center

Yes
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.
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.
