Sn2 mechanism: kinetics and substrate (video) | Khan Academy

- [Instructor] Let's look at the mechanism for an SN2 reaction. On the left we have an alkyl halide and we know that this bromine is a little bit more electronegative than this carbon so the bromine withdraws some electron density away from that carbon which makes this carbon a little bit positive, so we say partially positive.

Kinematic diagram - Wikipedia

A kinematic diagram or kinematic scheme illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic versions of the joints of the mechanism or machine. A kinematic diagram is sometimes called a joint map or a skeleton diagram.
