A.
It may exist entirely in the gauche conformation.
B.
It may exist as a mixture of anti and gauche conformations.
C.
It may exist entirely in the anti conformation.
The measured dipole moment of
ClCH2CH2Cl
is 1.12 D. Which one of the following statements about
1,2−dichloroethane
is false?
Homework Answers
False statement is
C.
It may exist entirely in the anti conformation.
In anti conformation both electronegative chlorines are in opposite direction; and it dipole moment will be cancelled.
Add Answer to:
A.
It may exist entirely in the gauche conformation.

9.78 The two lowest energy conformations of pentane are the anti-anti and the anti-gauche forms, in terms of arrangements around the two central C─C bonds. A recent study analyzed the conformations of 3-heptyne as an “elongated” analogue of pentane, where a carbon-carbon triple bond is “inserted” between C2 and C3 of pentane.[15] Interestingly, the researchers found that in each of the two most stable conformations of 3-heptyne, C1 and C6 are nearly eclipsed (looking down the alkyne group). In one...
