Assertion : `P_4` is more reactive than `N_2`. Reason: P-P single bond in `P_4` is much weaker than `N-=N` in `N_2` molecule.

N-N single bond is weaker than P-P single bond.

Phosphorus ( P_(4) ) is more reactive than nitrogen ( N_(2) )

In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. (a) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion. (b) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion. (c) Assertion is correct, but reason is wrong statement. (d) Assertion is wrong but reason is correct statement. (e) Both assertion and reason are wrong statements. Assertion : N_2 is less reactive than P_4 . Reason : Nitrogen has more electron gain enthalpy than phosphorus.

State reasons for the following: The N-O bond in NO_2^- is shorter than the N-O bond in NO_3^- .

p-methoxyaniline is a stronger base than aniline but p-nitroaniline is a weaker base than aniline. Explain.

Assertion: p-nitroaniline is a stronger base than p-toluidine. Reason : The electron withdrawing -NO_2 group in p-nitroaniline makes it a stronger base.

Let P(n) denote the statement that n^2+n is odd . It is seen that P(n)rArr P(n+1),P(n) is true for all

Let S be the sum, P the product and R the sum of reciprocals of n terms in a G.P. Prove that P^2R^n = S^n .

What is transistor ? Give the symbols of n-p-n and p-n-p transistor.

Give reasons for the following : At room temperature, N_2 is much less reactive.
