Why is it possible to observe them only in an acidic environment? Carbocations are acids according to Bronsted-Lowry, that is they are proton donors. In particular, they are very strong acids, with pKa values ​​comparable to strong inorganic acids such as HCl or H2SO4. As such, they are deprotonated in basic solution. The neutral species corresponding to the carbocatione is ...

Moreover it is called plane two-dimensional flow if the flow lines in addition to being contained in some planes have the latter all parallel to each other. For example, the motion around a sphere is a two-dimensional (non-plane) motion. The flow line (or current) is defined as the trajectory of a fluid lagrangic element, tangent point by point at velocity v.
