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...

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...
