Question

Consider the following two compounds:
Identify which of these two compounds has greater resonance stabilization.

Answer 1

$5$ Resonance structures for $1^{st}$ compound, see the figure 1.

$6$ Resonance structures for $2^{nd}$ compound. See the figure 2.

Since, more resonance structures implies more resonance stabilization, $2^{nd}$ compound is more stable than $1^{st}$ compound.
