Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

From the plural form: This is a redirect from a plural noun to its singular form.
- This redirect link is used for convenience; it is often preferable to add the plural directly after the link (for example, [[link]]s). However, do not replace these redirected links with a simpler link unless the page is updated for another reason (see WP:NOTBROKEN).
- Use this rcat to tag only mainspace redirects; when plural forms are found in other namespaces, use {{R from modification}} instead.

From an avoided double redirect: This is a redirect from an alternative title or related topic of EnoneEnone, another redirect to the same title. Because double redirects are disallowed, both pages currently point to Α,β-Unsaturated carbonyl compound#Enones.
- If EnoneEnone is retargeted or is expanded into a separate article, template, or other project page, this redirect will be recategorized to be updated.

To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}} instead.

When appropriate, protection levels are automatically sensed, described and categorized.
