In resonance

Which of the following statements is (are) true about resonance. (a) Resonance is an intramolecular process. (b) Resonance involves delocalization of both sigma " and " pi electrons. (c )Resonance involves delocalization of pi electrons and lone pair only. (d) Resonance decreases potential energy of a molecule. (e ) Resonance has no effect on the potential energy of a molecule. (f)Resonance is the only way to increase molecular stability. (g) Resonance is not the only way to increase molecular stability. (h) Any resonating molecule is always more stable than any nonresonating molecule. (i) The canonical structure explains all features of a molecule. (j) The resonance hybrid explains all features of a molecule. (k)Resonating structures are real and resonance hybrid is imaginary. (l) Resonance hybrid is real and resonating structures are imaginary. (m) Resonance hybrid is always more stable than all canonical structures.

The first resonance length of a resonance tube is 40 cm and the second resonance length is 122 cm . The third resonance length of the tube will be

If a 0.03 H inductor, a 10 Omega resistor and a 2muF capacitor are connected in series. At what frequency will they resonate? What will be the phase angle at resonance?

The end correction of a resonance column in resonance tube experiment is 0.5 cm. If the shortest length resonating with a tuning fork is 16 cm, then the next resonating length will be
