Given below are two statements. Statement I : The dipole moment of 4 CH ₃ - 3~~~~ CH = 3~~~~ CH - 1~~~~ CH = O is greater than 4 CH ₃ - 3 CH ₂ - 2 CH ₂ - 1 CH = O Statement II : C ₁- C ₂ bond length of 4 CH ₃- 3 CH= 2 CH - CH = O is greater than C ₁- C ₂ bond length of In the light of the above statements, choose the correct answer from the options given below:
Options
- AStatement I is false but Statement II is true
- BBoth Statement I and Statement II are false
- CStatement I is true but Statement II is false
- DBoth Statement I and Statement II are true
Correct answer
C. Statement I is true but Statement II is false
Step-by-step solution
Statement-I : = q d More charges and more distance between charges than other compound so more dipole moment. Statement-I is true. Statement-II : C ₁- C ₂ bond has partial double bond character that means lesser bond length than C ₁- C ₂ bond of other compound. Statement-II is false.
