Given below are two statements.
Statement I : The dipole moment of ${}^{4}\mathrm{C}\mathrm{H}_3-{}^{3}\mathrm{C}\mathrm{H}={}^{2}\mathrm{C}\mathrm{H}-{}^{1}\mathrm{C}\mathrm{H}=\mathrm{O}$ is greater than ${}^{4}\mathrm{C}\mathrm{H}_3-{}^{3}\mathrm{C}\mathrm{H}_2-{}^{2}\mathrm{C}\mathrm{H}={}^{1}\mathrm{C}\mathrm{H}=\mathrm{O}$
Statement II : $C_1-C_2$ bond length of ${}^{4}\mathrm{C}\mathrm{H}_3-{}^{3}\mathrm{C}\mathrm{H}={}^{2}\mathrm{C}\mathrm{H}-{}^{1}\mathrm{C}\mathrm{H}=\mathrm{O}$ is greater than $C_1-C_2$ bond length of ${}^{4}\mathrm{C}\mathrm{H}_3-{}^{3}\mathrm{C}\mathrm{H}_2-{}^{2}\mathrm{C}\mathrm{H}={}^{1}\mathrm{C}\mathrm{H}=\mathrm{O}$
In the light of the above statements, choose the correct answer from the options given below:
Statement I is false but Statement II is true
Both Statement I and Statement II are false
Statement I is true but Statement II is false
Both Statement I and Statement II are true
Solution
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 than $\mathrm{C}_1-\mathrm{C}_2$ bond of other compound. Statement-II is false.
