Answer is: C) N.
Nitrogen (N) has greatest electronegativity.
Electronegativity (χ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
Nitrogen has electronegativity χ = 3 and other elements have less.
has the greatest attraction for electrons in a chemical bond.
Further explanation:
Electronegativity:
It is the tendency of an atom to attract the shared electrons in the bond towards itself. More the electronegativity of the atom, higher will be its tendency to attract the bonding electrons towards itself. The electronegative atom develops a partial negative charge and the electropositive atom develops a partial positive charge.
Electronegativity trends in the periodic table:
Along the period, electronegativity increases due to the increase in the nuclear charge. This results in the strong attraction of electrons.
Down the group, electronegativity decreases due to an increase in the size of elements. This results in a lesser attraction between the nucleus and the electron.
All the given elements (As, Bi, N, P) are present in the same group of the periodic table. Nitrogen is present at the top of the group so it has the highest electronegativity among the given elements. Phosphorus is present below nitrogen but above As and Bi so its electronegativity is less than nitrogen but more than the remaining elements. Arsenic is present above Bi so it has more electronegativity than Bi. Bismuth is present at the bottom of the group so it has the least electronegativity among the given elements.
Therefore, nitrogen has the greatest tendency to attract electrons towards itself in a chemical bond.

(2) 0.1 M KOH (4) 0.1 M H2SO4
Answer: (2) 0.1 M KOH
Explanation:
Thymol blue is an universal indicator. Thymol blue has a blue color when in basic conditions (pH > 7), a green color in neutral conditions (pH =7), and a yellow color in acidic conditions (pH < 7).
pH or pOH is the measure of acidity or alkalinity of a solution. pH is calculated by taking negative logarithm of hydrogen ion concentration.
0.1 M , 0.1 M and 0.1 M are all acidic in nature.
Thus thymol blue will appear blue in basic 0.1 M KOH.
b) false
b)gains electrons and gains potential
c)energy gains electrons and loses potential energy
d)loses electrons and gains potential energy
Answer : The correct option is a) Loses electrons and loses potential energy.
Explanation :
Reducing agent : In a redox reaction, it is oxidized by the loss of electrons and by the loses of potential energy. It is also called as electron donor.
Reducing agent reduces others by loss of electron and its oxidation state increases.
For example : Sodium is a reducing agent and itself oxidized as follows,
Therefore, the molecule that function as a reducing agent in a redox reaction is loses electrons and loses potential energy.
Final answer:
In a redox reaction, the reducing agent loses both electrons and potential energy. This process results in oxidation of the reducing agent as the oxidation state of the reducing agent increases.
In a redox or oxidation-reduction reaction, the molecule acting as the reducing agent (or electron donor) loses electrons and loses potential energy. Hence, the correct option is a). The reducing agent donates electrons to another substance or molecule and, in this process, is itself oxidized. The oxidation state of the reducing agent increases. The reduction process involves a gain of electrons, but this gain happens to the substance that receives the electrons, not the one who donates them (the reducing agent).
