In this question, we need to determine the species that has carbon with a sextet of electrons and can act as an electrophile. Let's analyze the given options:
Based on this analysis, the correct answer is carbocation, since it has a sextet of electrons and typically acts as an electrophile due to its electron-deficient nature.
Carbocations have a carbon atom with a sextet of electrons, making them electron-deficient and capable of acting as electrophiles.

Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).

In the first configuration (1) as shown in the figure, four identical charges \( q_0 \) are kept at the corners A, B, C and D of square of side length \( a \). In the second configuration (2), the same charges are shifted to mid points C, E, H, and F of the square. If \( K = \frac{1}{4\pi \epsilon_0} \), the difference between the potential energies of configuration (2) and (1) is given by:
