Question 11.3: Draw line-angle formulas for the five constitutional isomers...
Draw line-angle formulas for the five constitutional isomers with the molecular formula C_{6}H_{14}.
Strategy
In solving problems of this type, you should devise a strategy and then follow it. Here is one possible strategy. First, draw a line-angle formula for the constitutional isomer with all six carbons in an unbranched chain. Then, draw line-angle formulas for all constitutional isomers with fi ve carbons in a chain and one carbon as a branch on the chain. Finally, draw line-angle formulas for all constitutional isomers with four carbons in a chain and two carbons as branches.
Here are line-angle formulas for all constitutional isomers with six, fi ve, and four carbons in the longest chain. No constitutional isomers for C_{6}H_{14} having only three carbons in the longest chain are possible.
