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.


In the given figure, the blocks $A$, $B$ and $C$ weigh $4\,\text{kg}$, $6\,\text{kg}$ and $8\,\text{kg}$ respectively. The coefficient of sliding friction between any two surfaces is $0.5$. The force $\vec{F}$ required to slide the block $C$ with constant speed is ___ N.
(Given: $g = 10\,\text{m s}^{-2}$) 
The equivalent resistance between the points \(A\) and \(B\) in the given circuit is \[ \frac{x}{5}\,\Omega. \] Find the value of \(x\).
