In Part 1, draw a mechanism for the reaction of butan-2-ol with sodium amide. In the box to the left, draw any necessary curved arrows. Show the products of the reaction in the box to the right.

Loose sediment moves downhill, usually into a low place where there's water, like a lake or the ocean. Layers of sediment begin to build up in the water. Over time, all those layers press on the layers below, compacting the sediment at the bottom.
