Given below are two statements. Statement I: The dipole moment of 4 CH_3 - 3 CH = 2 CH - 1 CH = O is greater than 4 CH_3- 3 CH_2 - 2 CH_2 - 1 CH = O…
Given below are two statements.
Statement I: The dipole moment of $\displaystyle \stackrel{4}{\mathrm{CH}_3}-\stackrel{3}{\mathrm{CH}}=\stackrel{2}{\mathrm{CH}}-\stackrel{1}{\mathrm{CH}}=\mathrm{O}$ is greater than $\displaystyle \stackrel{4}{\mathrm{CH}}_3-\stackrel{3}{\mathrm{CH}_2}-\stackrel{2}{\mathrm{CH}_2}-\stackrel{1}{\mathrm{CH}}=\mathrm{O}$Statement II: $\displaystyle \mathrm{C}_1-\mathrm{C}_2$ bond length of $\displaystyle \underset{4}{\mathrm{CH}_3}-\underset{3}{\mathrm{CH}}=\underset{2}{\mathrm{CH}}-\underset{1}{\mathrm{CH}}=\mathrm{O}$ is greater than $\displaystyle \mathrm{C}_1-\mathrm{C}_2$ bond length of $\displaystyle \underset{4}{\mathrm{CH}_3}-\underset{3}{\mathrm{CH}_2}-\underset{2}{\mathrm{CH}_2}-\underset{1}{\mathrm{CH}}=\mathrm{O}$
In the light of the above statements, choose the correct answer from the options given below:
