Disband and disperse both break a gathering apart, with a difference in what and how. Disband is to break up an organized group so that it no longer exists, its members going their separate ways. Disperse is to spread a gathered crowd, substance or mass out over a wide area until it thins. Disband ends an organized group; disperse spreads a gathering out.
Both break a gathering up, but disband ends a body and disperse spreads a mass. Disband, literally 'to un-band', winds up an organized group so its members leave — a deliberate ending of a body with a structure. Disperse, from dis- 'apart' and spargere 'to scatter', spreads a gathered crowd or mass out over a wide area. A committee disbands by a vote; a crowd is told to disperse. One dissolves a structured group; the other thins any gathering out across space.
disband
To disband is to break up an organized group so that it no longer exists — a band, a team, an army, a committee — and for its members to disperse and go their separate ways. Built from dis- 'apart' and band in its old sense of 'a company bound together', it is usually deliberate and often formal: a leader disbands a unit, or a body votes to disband itself. It can be transitive (they disbanded the choir) or intransitive (the choir disbanded). Close to dissolve, but disband stays with people and organizations.
disperse
To disperse is to break up a gathering and spread it out until it thins away — movement from concentration to diffusion. A crowd disperses when a concert ends; wind disperses seeds and smoke; light disperses through a prism. The word works both ways — things disperse on their own or are dispersed by some force — but it leans toward an even, gradual spreading that often fades to nothing, rather than a sudden, random fling. What was massed in one place ends up thinly distributed across many.

Ask whether an organized group is ended or a gathering is spread out. Disband stands a structured group down for good — a formation loosening on a signal, members walking off. Disperse spreads any gathering out over a wide area — a dandelion head flung the width of a field. If an organized group is wound up, that is disband; if a gathering thins out across space, that is disperse.

Disband ends an organized group with a structure — a band, an army, a committee; disperse spreads any gathering out over an area, including formless things like smoke. A group can be both disbanded (as a body) and dispersed (its members spread out), but disband stresses the end of the structure, disperse the spreading across space.
A useful pair for writing about groups breaking up. Disband is the deliberate, official word for an organized body ending — 'the unit was disbanded'; disperse is for spreading a gathering out — 'the crowd dispersed', 'ordered to disperse'. Examiners reward the difference: disband ends a structured group, disperse thins any gathering across space. The nouns are disbandment and dispersal.
