Ryan C., I got your two answers for my worksheet, thank you. However, number 18 isslightly cut off at the bottom(attached it again). The only part of it cut off are two different forms of a hexane (I believe) connected to NHC3 with the H underlined. the first (left) cyclohexane has only single bonds in it’s structure, the second (right) has 3 double bonds in it’s structure. Also, in number 19 you may have copied the bond line formation wrong… unless I don’t understand… there may be 17 carbons making it a heptadecane?,Oh, and number 19 asks for the molecular formula ( that part might have been cut off sorry ).,can you help do 18?,cyclohexane with alternating double bonds = benzene?
