Carbocation is a positively charged carbon ion(C+). It is an intermediate generally formed during organic reactions. They exhibit a special quality called 'rearrangement' by virtue of which less stable carbocations can rearrange to form more stable carbocations during the reaction. The actively ...

Why does carbocation stability increase in the order 1°, 2°, 3°?

I'm reading about $\:\mathrm{S_N1}$ and $\:\mathrm{S_N2}$ reaction mechanisms. 1° carbocations are unstable to the point of not having been observed in solution, ever. 2° are more stable, and 3° ...

Resonance in carbocation derived from allenes

During a reaction if addition on one of the $\pi$ bonds of an allene(containing even number of $\pi$ bonds like $\ce {H2C=C=CH2}$) takes place then a carbocation is formed. To decide the position of ...

Preparation of alkyl halide from alcohols

$\ce{R-OH + HBr -> R-Br + H2O}$ An $\ce{R+}$ carbocation is formed during this reaction. If $\ce{R}$ is any alkyl group instead of methyl or ethyl, can the beta hydrogen to the hydroxy group be ...

Why are isomers difficult to separate?

I recently learned that attempts to compare the spectra of two isomers of $C_3H_3^+$ were frustrated by the difficulty of separating the two species. What makes these isomers difficult to separate?

Precedence of 1,2 carbocation rearrangement

How can one choose which group has more shifting tendency in 1,2 carbocation rearrangement? The obvious order is via the stability of the carbocation of the group. But, phenylic groups have high ...
