Current Question (ID: 10908)

Question:

$\text{Compare the stability of the two resonating structures given below and mark the correct option:}$ $\text{H}_3\text{C}=\text{C}-\text{C}=\text{O} \leftrightarrow \text{H}_3\text{C}^+-\text{C}=\text{C}-\text{O}^-$ $\text{(I)} \hspace{50pt} \text{(II)}$

Options:

1. $\text{(I) is more stable than (II)}$ (Correct)
2. $\text{(II) is more stable than (I)}$
3. $\text{(I) and (II) both have the same stability}$
4. $\text{None of the above}$

Solution:

$\text{Hint: Neutral molecule is always stable than a charged molecule.}$ $\text{Resonance structures are a set of two or more Lewis structures that collectively describe the electronic bonding a single polyatomic species including fractional bonds and fractional charges.}$ $\text{The structure having more covalent bonds in a resonating structure has more stability. Further, there is a charge separation in structure (II) and the terminal carbon has only a sextet of electrons in (II). These two factors makes structure (II) less stable.}$ $\text{CH}_2=\text{CH}-\text{CH}=\text{O} \leftrightarrow \text{CH}_2-\text{CH}=\text{CH}-\text{O}^-$ $\text{I} \hspace{50pt} \text{II}$ $\text{Hence, I>II in terms of stability.}$
