What does a double bond between two atoms represent in terms of the number of electrons shared? What does a triple bond represent? When writing a Lewis structure, explain how we recognize when a molec...
See AnswerQ: When naming cycloalkynes that lack any other functional groups, the triple
When naming cycloalkynes that lack any other functional groups, the triple bond does not require a locant, because it is assumed to be between C1 and C2. Draw the structure of (R)-3-methylcyclononyne....

Upon treatment with aqueous acid, compound 1 is converted into compound 2. a. In the first step of the accepted mechanism, one of the triple bonds is protonated to give a vinyl carbocation. Generally...
See AnswerQ: Halogenation of alkynes with Cl2 or Br2 can generally be achieved with
Halogenation of alkynes with Cl2 or Br2 can generally be achieved with high yields, while halogenation of alkynes with 2 typically gives low yields. However, the following reaction is successfully com...
See AnswerQ: The two lowest energy conformations of pentane are the anti-anti
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-he...
