Turning our attention from the leaving group to the carbon moiety, it is observed
that the structure of the resulting carbonium ion has a large effect upon the ease
of substitution. Suggest the relative stability of the carbonium ions, CH3'1', C2H5+

Nucleophilic attack by the aromatic substrate on the carbonium ion of the solvent-
separated ion-pair (X) is ruled out by product analysis. For example, in the
alkylation of monosubstituted benzenes with a series of alkyl halides RC1, RBr
and RI ...
Formation of the third most abundant product (XXXV) also apparr ently involves
the intermediate formation of carbonium ion (XXX) by way of the addition of the
tertiary carbonium ion to tert-butyl ethylene. The ion apparently undergoes the
shift ...

They are formed by heterolytic bond fission. sp2 Hybridized :Z Carbonium ion
where Z is more electronegative than carbon. The positively charged carbon
atom in a carbonium ion uses sp2 hybrid orbitals to form three a bonds (Fig. 6.2).

Arun Bahl. The positively charged carbon atom in a carbonium ion uses sp2
hybrid orbitals to form three σ bonds (Fig. 3.1). A vacantp orbital extends above
and below the plane of the σ bonds. This vacantp orbital makes the carbon atom

Carbonium ions are extremely reactive and undergo a wide variety of reactions
according to specific rules regarding formation, rearrangement, and reaction. The
principal rules have been described by Voge [19] and are: 1. A carbonium ion ...

TERMINOLOGY FOR A POSITIVELY CHARGED CARBON [C+] How are the
terms CARBOCATION, CARBONIUM ION, and CARBENIUM ION different if they
are? CARBONIUM ION: The suffix 'onium' is used for naming a cation formed by ...
BHUPINDER MEHTA, MANJU MEHTA, 2005
Therefore, any factor that tends to spread out the positive charge of the electron-
deficient carbon and distribute it over the rest of the ion must stabilize a
carbonium ion. Consider a substituent G, attached to an electron-deficient carbon
.

The ionic intermediate carrying a positive charge at the central carbon atom is
known as carbonium ion. The ionic species in which central carbon atom is
negatively charged is known as carbanion. Carbonium ion and carbanion are
generally ...
