Homework Answers
Lets show the gauche and anti conformation.
H -bonding is present in gauche conformation and not in Anti due to the orientation of OH group. H-bond makes gauche conformation more stable.

Challenge Problem 09.78 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 (J. Phys. Chem. A. 2007, 111, 3513-3518). Interestingly, the researchers found that in each of the two most stable conformations of 3-heptyne, C1 and C6 are...

The anti conformation of 1, 2-dichloroethane, Cl-CH_2-CH_2- Cl, is 4.81 kJ mol^-1 (1.15 kcal mol^-1) more stable than the gauche conformation. The two energy barriers (measured relative to the energy of the gauche conformation) for carbon-carbon bond rotation are 21.5 kJ mol^-1 (5.15 kcal mol^-1) and 38.9 kJ mol^-1(9.3 kcal mol^-1). Sketch a graph of potential energy versus dihedral angle about the carbon-carbon bond. Show the energy differences on your graph and label each minimum and maximum with the appropriate...

When water is added to ethylene glycol, the viscosity of the solution decreases when compared to pure ethylene glycol. Which of the following is the BEST explanation of why this occurs? Ethylene glycol is thick and water is thin, so when mixed together it makes a medium thick solution The water molecules increase the intermolecular interactions between the ethylene glycol molecules, which allow them interact with other molecules, the resulting solution less viscous. The water molecules increase the intermolecular interactions...

Be sure to answer all parts. How many liters of the antifreeze ethylene glycol [CH2(OH)CH2(OH)] would you add to a car radiator containing 7.25 L of water if the coldest winter temperature in your area is -21.0°C? Calculate the boiling point of this water-ethylene glycol mixture. (The density of ethylene glycol is 1.11 g/mL.) What is the volume of antifreeze? L. What is the boiling point of the solution? oC
