Question 23.4: Determine the condensed formula, molecular formula, and name......

STRATEGY AND SOLUTION

Step 1. Determine the carbon backbone. Find the number of carbon atoms by counting the number of vertices or endpoints and draw the backbone of carbon atoms. Add multiple bonds in the correct location.

C  —  \overset{\overset{C}{|}}{C}  —  C  —  C\equiv C

Step 2. Satisfy the octet rule by adding bonds to hydrogen. Fulfill the octet for carbon by adding single bonds to hydrogen so that each carbon has a total of four bonds. To determine the molecular formula simply count up the atoms in the complete electron-dot structure.
