Some isomers lack optical activity because they have a plane of symmetry or a center of symmetry that results in the molecule being superimposable on its mirror image. This makes them achiral and unable to rotate the plane of polarized light, thus lacking optical activity.

How many non cyclic isomers are there for hexene?
There are more than 20 stuctural isomers of hexene C6H12, including various branched (cis and trans) and cyclic compounds (eg. cyclohexane, methyl-cylopentane, 1,1-dimethyl-cyclobutane, 1,2-dimethyl-cyclobutane, 1,3-dimethyl-cyclobutane, and some other, maybe not stable, propyl/methyl-ethyl/trimethyl-cyclopropanes) Some of them also count for optical isomerism (eg. 3*-methyl-1-pentene)
What are the various subgroups of structural isomers?
Structural Isomers- differ in the covalent arrangement of their atoms Geometric Isomers- differ in spatial arrangement around double bonds Enantiomers- mirror images of each other
What are some membrane bound organeles that bacteria lack?
because all the prokaryotes lack the membranous organelles, bacteria are also prokarotes so the lack those
Why some phonons are called optical phonon?
Optical phonons are modes where the ions in the crystal lattice move in a way that involves a change in the material's polarization. These phonons interact strongly with light, leading to changes in the material's optical properties. The energy of optical phonons corresponds to the energy of photons in the optical frequency range.
What is the difference between optical isomer and optically active isomer?
Optical isomers are molecules that are mirror images of each other and are non-superimposable. Optically active isomers are molecules that rotate the plane of polarized light. All optical isomers are optically active, but not all optically active isomers are optical isomers.

How many isomers does pentanol have?
12 isomers can be formed. 1-pentene cis-2-pentene and trans-2-pentene 2-methyl-1-butene 3-methyl-1-butene 2-methyl-2-butene 1,1-dimethylcyclopropane (1R, 2R)-1,2-dimethylcyclopropane (1S, 2S)-1,2-dimethylcyclopropane methylcyclobutane cyclopentane and ethylcyclopropane
What isomers that are mirror images of each other?
Chiral molecules have mirror-image isomers

What is the term for extreme optical fidelity?
One term that is used for extreme optical fidelity is resolution, however, there are other variables that come into play, as well. Another is MTF, or modulation transfer function and yet another phrase is lack of impurities. Some others are distortion and color purity.
What is some information on optical illusions?
optical illusions are an object causing false impressions
What is reason for Physical activity drop out?
There are several reasons why a person may stop participating in a specific physical activity. Some of those possible reasons are injury or health issues, lack of time or resources needed to continue.
What is an easy definition of the optical axis?
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope..
What is optical hardware?
Optical networking hardware entails the various components used in optical technologies. Some of the common hardware include routers, optical fiber, electronic devices and so much more.
