Structural isomers also called constitutional isomers are different compounds that have same molecular formula but different molecular structure. Structural isomers have same number of each type of atoms but the atoms are connected in a different order in them.
Structural isomerism is seen in organic compounds. It can be due to different arrangement of carbon chain, due to different position of functional group on the carbon chain, due to different functional groups that give their family of compounds same molecular formula.
Difference in arrangement of atoms is visible if structural formulas are written for compounds having same molecular formula.
Like structural isomers, stereoisomers also have same molecular formula. Stereoisomers are not structural isomers. Stereoisomers have their atoms connected in same sequence( same constitution), but they differ in the arrangement of atoms in space.
Cis and trans isomers of alkenes are examples of stereoisomers. Carbon chain arrangement, position of functional groups, and everything that could be different in structural isomerism is same here.
Structural (or constitutional isomers) share the same numbers and kinds of atoms. However, the bonding pattern between the atoms differs. For example, dimethyl ether and ethanol both have the chemical formula of C2H6O, but their structures are different.
dimethyl ether H3C - O - CH3
ethanol H3C - CH2 - OH
Structural isomers have the same molecular formula but different connectivity. Optical isomers have the same molecular formula but rotate plane polarized light. Optical isomers occur when chiral centers exist in a molecule giving rise to enantiomers. Enantiomers are molecules with non-superimposable mirror images. One enantiomer will rotate plane polarized light in the clockwise direction and the other will rotate it in the counterclockwise direction.
Constitutional isomers- same formula, attached differently
enatiomers- mirror images but not the same molecule
diastereomers- anything that's not an enatiomer or constitutional. Not the same molecule either.
structural isomers different each other is different compound with same molecular each other mean that different other of attachment of their atom can be said as constituent isomer.
Structural isomers are chemical compounds that have the same molecular formula but different arrangements, that create two totally different compounds.
These are not optical isomers they are functional group isomers a subcategory of structural isomers.

Optical isomers are found only if there is chiral centre. There is no chiral centre in CH2ClBr due to the presence of two hydrogens on a single carbon.

L and D amino acids are both optical isomers of each other and only differ in their ability to rotate plane polarized light in opposite directions.
These are not optical isomers they are functional group isomers a subcategory of structural isomers.
Optical isomers are isomers of molecules which are non-superimposible. They have a left hand and a right hand and this is how you distinguish between them.
l ascorbic acid and d ascorbic acid are optical isomers of each other. Optical isomers have the same physical and chemical properties but bend the plane of polarisation of polarized light in different directions.It is also called ChiralitySee the related link for more info on optical isomers.
Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.
