ELI5: Explain Like I'm 5

SN1 reaction

Imagine you have a toy block with two different colors, red and blue. You want to take off the blue part, but it's kind of stuck to the red part.

In chemistry, this is kind of like when we want to take away a part of a molecule, but it's attached to the other part too strongly.

In an sn1 reaction, we use a special chemical (let's call it a toy grabbing tool) to help us separate the two parts of the molecule. The toy grabbing tool helps break the bond between the two parts, so we can easily take away the part we don't want.

But wait, there's more! This reaction has two steps. In the first step, the toy grabbing tool helps break the bond. Then, in the second step, we add another chemical to help the two parts of the molecule come back together in a new way (kind of like playing with toy blocks AGAIN, but rearranging them differently).

Overall, the sn1 reaction helps us "grab" the part of the molecule we want to remove by breaking the bond between the two parts and rearranging the molecule in a new way.
