Answer : Option D) .
Explanation : A delocalized π bond are those π bonds in which the electrons are allowed to move freely over more than two nuclei. So, amongst the given molecules is the correct answer. As is a molecule which shares a π bond between one carbon and three oxygen atom. The electrons move freely over the whole molecule.
Its C
a catalyst speeds up a reaction by offering the reaction an alternative reaction pathway with a lower activation energy

The question is incomplete. The complete question is stated below:
Two point charges are held at the corners of a rectangle as shown in the figure. The lengths of sides of the rectangle are 0.050 m and 0.150 m. Assume that the electric potential is defined to be zero at infinity.
a. Determine the electric potential at corner A.
b. What is the electric potential energy of a +3 µC charge placed at corner A?
Answer / Explanation:
a )V(A) = 1 / 4πe° ( - 5 5x10∧6C / 0.150m + 2x10∧6C / 0.050m )
The answer to the equation above is : = +6.0x10∧4 j/c
b) U(A) = qV(A)= (3.0x10∧6C) (6.0x10∧4 . j/c) =
The answer to the equation above is : =0.18 J
Explanation:
Where V(A) is equivalent to the electric potential
U(A) is equivalent to the electric potential energy
The first man-made element or artificial element which is produced because it is not found naturally in nature is Technicium, in 1937. Technicium has an atomic number of 43 and atomic mass of 98 g/mol.
