    We can say that benzene is nonpolar because it is a hydrocarbon that contains only C-C and C-H bonds, and hydrocarbons are nonpolar. But C is slightly more electronegative than H (by 0.35 units), so a C-H bond is very slightly polar and has a small dipole moment.

    The limiting reagent (or limiting reactant, LR) in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.

    N-type semiconductors are a type of extrinsic semiconductor where the dopant atoms are capable of providing extra conduction electrons to the host material (e.g. phosphorus in silicon). This creates an excess of negative (n-type) electron charge carriers.

    Both are able to pick up protons, but NH3 is a more polar molecule due to the dipoles between the hydrogen and the nitrogen. ... N is smaller than P thus it is a better lewis base, being able to form more stable sigma bonds. Both of these things cause NH3 to more readily take up a proton from solution.

    Difference Between p-Type and n-Type Semiconductor

    1. In a p-type semiconductor, the III group element of the periodic table is added as a doping element, whereas in n-type the V group element is the doping element.
    2. Trivalent impurity like Aluminium, Gallium, and Indium is added in the p-type semiconductor, while in the n-type semiconductor Pentavalent impurity like Arsenic, Antimony, Phosphorus, Bismuth, etc. are added.
    3. The impurity added in p-type semiconductor provides extra holes known as Acceptor atom, whereas in n-type semiconductor impurity provides extra electrons and termed as Donor atom.
    4. In a p-type semiconductor, the majority carriers are holes, and the minority carriers are electrons. In the n-type semiconductor, electrons are majority carriers, and holes are minority carriers.
    5. The electron density is much greater than the hole density in the n-type semiconductor denoted as ne >> nh whereas, in p-type semiconductor the hole density is much greater than the electron density nh >> ne.
    6. In an n-type semiconductor, the donor energy level is close to the conduction band and away from the valence band. In the p-type semiconductor, the acceptor energy level is close to the valence band and away from the conduction band.
    7. The Fermi level of the n-type semiconductor lies between the donor energy level and the conduction band while the Fermi level of the p-type semiconductor lies between the acceptor energy level and the valence band.
    8. Majority carriers move from higher to lower potential in p-type whereas, in n-type, the majority carriers move from lower to higher potential.
