Steps for 1.74 Propose at least two different structures for a compound with six carbon atoms that exhibits the following features: a. All six carbon atoms are
sp^(2)
hybridized. b. Only one carbon atom is
sp
hybridized, and the remaining five carbon atoms are all
sp^(3)
hybridized (remember that your compound can have elements other than carbon and hydrogen). c. There is a ring, and all of the carbon atoms are
sp^(3)
hybridized. d. All six carbon atoms are
sp
hybridized, and the compound contains no hydrogen atoms (remember that a triple bond is linear and therefore cannot be incorporated into a ring of six carbon atoms).
