JEE Mains · Chemistry · STD 11 - 8.4. Organic chemistry reaction mechanism
Given below are two statements.
Statement I : The dipole moment of \(\stackrel{4}{\mathrm{CH}_3}-\stackrel{3~~~~}{\mathrm{CH}}=\stackrel{3~~~~}{\mathrm{CH}}-\stackrel{1~~~~}{\mathrm{CH}}=\mathrm{O}\) is greater than \(\stackrel{4}{\mathrm{CH}_3}-\stackrel{3}{\mathrm{CH}_2}-\stackrel{2}{\mathrm{CH}_2}-\stackrel{1}{\mathrm{CH}}=\mathrm{O}\)
Statement II : \(\mathbf{C}_1-\mathbf{C}_2\) bond length of \(\underset{4}{\mathrm{CH}_3-\mathrm{}} \underset{3}{\mathrm{CH=}} \underset{2}{\mathrm{CH}}-\mathrm{CH}=\mathrm{O}\) is greater than \(\mathrm{C}_1-\mathrm{C}_2\) bond length of

In the light of the above statements, choose the correct answer from the options given below:
- A Statement I is false but Statement II is true
- B Both Statement I and Statement II are false
- C Statement I is true but Statement II is false
- D Both Statement I and Statement II are true
Answer & Solution
Correct Answer
(C) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
Statement-I : \(\mu=\mathrm{q} \times \mathrm{d}\) More charges and more distance between charges than other compound so more dipole moment. Statement-I is true. Statement-II : \(\mathrm{C}_1-\mathrm{C}_2\) bond has partial double bond character that means lesser bond length…
