Current Question (ID: 10917)

Question:

$\text{The major contributor to the resonance hybrid among the following resonance structures is-}$ $\text{(CH)}_3 - \text{(CH)}_2 - \text{CH} - \text{O}::(\text{CH})_3 \leftrightarrow$ $\text{(I)}$ $\text{(CH)}_3 - \text{(CH)}_2 - \text{CH} = \text{O}^\oplus(\text{CH})_3$ $\text{(II)}$

Options:

1. $\text{I}$
2. $\text{II}$ (Correct)
3. $\text{Both have equal contribution}$
4. $\text{They are not resonance structures}$

Solution:

$\text{Hint: If all atoms octet completed thus, it is more stable}$ $\text{The features that decreases the predicted stability of a contributing resonance structure as follows:}$ $\text{1. An atom with an incomplete octet}$ $\text{2. A negative charge that is not on the most electronegative atom or a positive charge that is not on the least electronegative atom}$ $\text{3. Charge separation}$ $\text{In the second structure, all atoms octet is complete. Hence, second structure is the most stable and option two is the correct answer.}$
