Current Question (ID: 10914)

Question:

$\text{The resonance hybrid structure will not exist for-}\n\text{a. } \text{CH}_3\text{OH}\n\text{b. } \text{R - CONH}_2\n\text{c. } \text{CH}_3\text{CH} = \text{CHCH}_2\text{NH}_2$

Options:

1. $\text{a, and c}$ (Correct)
2. $\text{a, and b only}$
3. $\text{only a}$
4. $\text{b and c only}$

Solution:

$\text{Hint: Application of resonance}\n\text{Explanation:}\n\text{Step 1: Find out the resonance}\text{a) } \text{CH}_3\text{OH} \text{ as it lacks pi-electrons hence it will not exist as a resonance hybrid.}\n\n\text{b) } \text{R - CONH}_2 \text{ due to the presence of n-electrons on N and pi electrons on C=O bond, hence amide can be represented as a resonance.}\n\n\text{c) } \text{CH}_3\text{CH} = \text{CHCH}_2\text{NH}_2 \text{ as the lone pair of electrons on the N- atom is not conjugated with the pi-electrons of double bond.}\n\n\text{Step 2: } \text{CH}_3\text{OH} \text{ and } \text{CH}_3\text{CH}=\text{CHCH}_2\text{NH}_2 \text{ will not show resonance}\n\n\text{Hence, the correct answer is option 1.}$
