Final answer:
The condensed structure of sec-butyl tert-butyl ether is (CH₃)₃CO(CH₃)₂CHCH₂, while its skeletal structure features an oxygen with two branches representing tert-butyl and sec-butyl groups. Isoheptyl alcohol has a condensed structure of (CH₃)₂CHCH₂CH₂CH₂CH₂OH and its skeletal structure presents a zigzag carbon backbone with an OH group at one end and two methyl groups branching at the third carbon.
Step-by-step explanation:
To draw the condensed structure and skeletal structure for sec-butyl tert-butyl ether and isoheptyl alcohol:
- Sec-butyl tert-butyl ether: it's an ether where the sec-butyl group ((CH₃)₂CHCH₂-) and tert-butyl group ((CH₃)₃C-) are connected via an oxygen atom. The condensed structure is (CH₃)₃CO(CH₃)₂CHCH₂. The skeletal structure consists of a central oxygen atom (often depicted simply as 'O') with two branching groups; one branch is a straight line with a 'V' on the end to represent the tert-butyl group, and the other branch represents sec-butyl as a line with two methyl groups dangling off the second carbon atom.
- Isoheptyl alcohol: this is an alcohol derived from isopentane with a total of 7 carbons. The condensed structure is (CH₃)₂CHCH₂CH₂CH₂CH₂OH. The skeletal structure would show a zigzag line representing the carbon backbone with one end terminating in an OH group to signify the alcohol, and at the third carbon from this end, two lines represent methyl groups branching off.
