Yes, allene is optically active due to its chirality. It has two chiral centers, resulting in four stereoisomers, two of which are enantiomers that are optically active.
Water is not optically active. It does not rotate the plane of polarized light, which is a characteristic typically associated with optically active substances.
No, phenylmethanol is not optically active because it lacks a chiral center. It does not have a stereocenter that would give rise to enantiomers.
Meso compounds contain an internal plane of symmetry, which results in equal and opposite optical rotations cancelling each other out, giving the appearance of optically inactive behavior. However, if the meso compound is resolved into its enantiomeric forms, each enantiomer will exhibit optical activity. Thus, meso compounds are considered optically active at the level of their enantiomers.
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.
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.

A substance is optically active if it has the ability to rotate plane-polarized light. This can be detected using a polarimeter, which measures the extent and direction of rotation caused by the substance. Optically active substances have chiral centers that do not have a plane of symmetry, making them capable of rotating the plane of polarized light.

Yes, enantiomers are optically active because they have a chiral center that causes them to rotate plane-polarized light in opposite directions.
Optically active substances are those that can rotate the plane of polarized light. Chiral molecules, which have a non-superimposable mirror image, are optically active. Examples include sugars like glucose and amino acids like alanine.
Alanine is optically active because it has a chiral center, which is essential for a molecule to be optically active.
