Thanks for your patience during our recent outage at scalar.usc.edu. While Scalar content is loading normally now, saving is still slow, and Scalar's 'additional metadata' features have been disabled, which may interfere with features like timelines and maps that depend on metadata. This also means that saving a page or media item will remove its additional metadata. If this occurs, you can use the 'All versions' link at the bottom of the page to restore the earlier version. We are continuing to troubleshoot, and will provide further updates as needed. Note that this only affects Scalar projects at scalar.usc.edu, and not those hosted elsewhere.

The substrate is the same, but the leaving group is not. When alcohols are put in acidic solutions, the OH can be protonated to make a better leaving group (R-OH2+ vs R-OH). In both E1 and E2 reactions, the type of leaving group affects the activation energy. The first reaction is faster. The substrates, leaving group, and nucleophile are the same, but the solvent is different. Protic solvents better solubilize the carbocation and leaving group, improving both species’ stability. In E1 reactions, the stability of the carbocation affects the activation energy.
