WebMay 5, 2015 · Very interesting question. This also popped up in my head once. And this is how I convinced myself. The confusing term here is stability. Tertiary carbocations are stable by inductive effect and hyper conjugation, and therefore have the tendency to sustain the positive charge on the carbon atom and stay like this for long. 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 …
