WebSo, a tertiary carbocation is more stable than a secondary. You can also see at this carbon now we have an sp3 hybridized carbon here, so the geometry around that carbon is tetrahedral. It went from being planar to tetrahedral geometry. Let's draw the hydride shift that we saw in the video. WebA carbanion can be defined as a negatively charged ion in which a carbon atom exhibits trivalence (implying it forms a total of three bonds) and holds a formal negative charge whose magnitude is at least -1.
