The dipole moment of 1, 2-Dichloroethane is 1.12 D. Which statement is correct about this compound.
A
It exists mainly in fully eclipsed conformation.
B
It exists only in anti conformation.
C
The polarity is due to gauche (skew) conformation.
D
The anti conformation has highest dipole moment.
Answer
The polarity is due to gauche (skew) conformation.
Explanation
Solution
Cl – CH2 – CH2 – Cl has two staggered conformations.
Gauche form
Only Gauche form is polar. Anti form is nonpolar.
