Question No.60
Indicate the wrong statement according to Valence bond theory:

• A. A sigma bond is stronger then $\pi$ - bond
• B. p-orbitals always have only sidewise overlapping
• C. s-orbitals never form $\pi$ - bonds
• D. There can be only one sigma bond between two atoms

Answer 1

Answer: (A)

A sigma bond is stronger then $\pi$ - bond

By Faraday second law, if the same amount of charge is passing through the solution connected in series for the same time then the amount of substances deposited is directly proportional to their equivalent weight. In dilute $H_2{SO}_4$, hydrogen is present at cathode and oxygen is present at the anode in their molecular form. Weight deposited is directly proportional to their equivalent weight.

So, the mass of hydrogen at the cathode: the mass of oxygen at anode = 2: 16 = 1: 8

So, the correct answer is option A.
