etühend

I’m not sure what you mean by “etühend.” This form does not appear as a standard term in common Estonian or English scientific literature, so I want to confirm the intended meaning before writing the article. It could be a misspelling or a partial form of one of several possibilities.

Possible interpretations to choose from:

- Etüleen-based compound (ethene/ethylene chemistry): If you meant a general category of compounds containing the ethylene motif or derivatives, I can write a concise wiki-style article explaining definition, classes, examples, properties, and typical uses.

- Disconnection or non-connection term (etühendus): If you intended a concept related to absence of connection in networks, electronics, or linguistics, I can draft an article outlining its meaning and contexts.

- Ethyl-related compound (etüül- chemistry): If you meant compounds bearing the ethyl group (etüül), I can cover examples like ethyl derivatives, naming, and common reactions.

- A different or project-specific term: If you have a source, spelling, or field (biology, physics, programming, etc.), please share.

Please tell me which interpretation you want, or provide a source or context, and I’ll generate a concise wiki-style article under 300 words.
