1-bromobutane and 2-bromobutane are structural isomers as they differ in the position of the bromine atom.

1-butanol and 2-butanol differ in the position of the hydroxyl group, hence they are structural isomers.

1-Butene and 2-Butene are structural isomers as they differ in the position of the double bond.

1-butyne and 2-butyne are structural isomers as they differ in the position of the triple bond.

Alkenes exhibit geometric isomerism due to the restricted rotation around the double bond.

Butanol can exist in different structural forms (1-butanol and 2-butanol), which is a case of structural isomerism.

Butanol and isobutanol are structural isomers as they have the same molecular formula but different structures.

Butene exhibits geometric isomerism (cis-trans isomerism) due to the presence of a double bond.

Butene exhibits geometric isomerism due to the restricted rotation around the double bond.

Structural isomerism occurs when compounds have the same molecular formula but different arrangements of atoms.

Structural isomerism occurs when compounds have the same molecular formula but different structural arrangements.

Ortho, meta, and para derivatives of disubstituted benzene are examples of positional isomerism.

Secondary amines can exhibit structural isomerism due to different alkyl groups attached to the nitrogen.

CH3NH2 (methylamine) and C2H5NH2 (ethylamine) exhibit structural isomerism as they have different carbon skeletons.

The complex [Co(en)2Cl2]+ can exhibit optical isomerism due to the presence of bidentate ligands (en = ethylenediamine) which can create non-superimposable mirror images.

[Co(en)3]Cl3 shows optical isomerism because it has chiral centers due to the bidentate ligand ethylenediamine (en).

Geometric isomerism occurs due to different arrangements of ligands around the central metal ion.

The complex [Cr(en)2Cl2]+ can show optical isomerism due to the presence of bidentate ligands (en = ethylenediamine) which can create non-superimposable mirror images.

The complex [Cr(en)3]3+ shows optical isomerism because it contains bidentate ligands (en = ethylenediamine) that can create non-superimposable mirror images.

[Co(en)3]3+ exhibits optical isomerism because it has chiral centers due to the bidentate ligand ethylenediamine (en).

The isomerism shown by [Co(NH3)5Cl]Br is coordination isomerism, where the composition of the complex changes.

[Cr(en)3]3+ shows optical isomerism because it has chiral centers due to the bidentate nature of the ethylenediamine (en) ligands.

Coordination isomerism occurs when the composition of the coordination sphere differs, as seen in this complex.

The Freundlich equation describes a type of adsorption isotherm that is applicable to heterogeneous surfaces.

Pivot joints allow for rotational movement, as seen in the neck.

Ball-and-socket joints, such as the shoulder and hip joints, allow for the greatest range of motion.

The elbow is a hinge joint, allowing movement in one plane, primarily flexion and extension.

The shoulder joint is a ball and socket joint, allowing for a wide range of motion.
