Question

multiple choice 2 points
which of the following condensed formulas represents the same compound as the line - angle structure shown?
ch3ch2och2n(ch2ch2ch3)2
ch3ch2ch2och2n(ch2ch3)2
ch3ch2och2n(ch2ch3)2
ch3ch2ch2och2ch2ch2n(ch2ch2ch3)2

Explanation:

Step1: Analyze line - angle structure

The line - angle structure has an oxygen bonded to a three - carbon chain on one side and a nitrogen bonded to two three - carbon chains on the other side. The carbon bonded to the oxygen has two more carbons in its chain.

Step2: Match with condensed formulas

The correct condensed formula should represent the same connectivity. CH₃CH₂CH₂OCH₂N(CH₂CH₂CH₃)₂ has the correct connectivity of atoms as in the line - angle structure.

Answer:

CH₃CH₂CH₂OCH₂N(CH₂CH₂CH₃)₂
