What is the condensed structural formula for 3-isopropyl-2-hexene
The Correct Answer and Explanation is:
Condensed Structural Formula for 3-Isopropyl-2-hexene:
CH₃CH=C(CH(CH₃)₂)CH₂CH₃
Explanation
To determine the condensed structural formula of 3-isopropyl-2-hexene, we must understand its name using IUPAC rules, which reveal the structure of the compound step by step.
Step 1: Identify the parent chain
- The base name is hexene, which tells us:
- The compound is an alkene (has a carbon-carbon double bond).
- It contains six carbon atoms in the longest continuous chain.
- The double bond starts at carbon 2 (as indicated by “2-hexene”).
So the main carbon chain looks like this:
CH₃–CH=CH–CH₂–CH₂–CH₃ (this is 2-hexene).
Step 2: Add the substituent
- There is an isopropyl group on carbon 3.
An isopropyl group is:
–CH(CH₃)₂
(It has a central carbon bonded to two methyl groups and the main chain.)
We now place this group on carbon 3 of the chain. The parent chain numbering goes from left to right to keep the double bond at carbon 2 (the lowest possible number for the double bond).
The backbone with carbon numbers:
- CH₃
- CH=
- C(CH(CH₃)₂)
- CH₂
- CH₃
So, integrating all:
- Carbon 1: CH₃
- Carbon 2: CH=
- Carbon 3: C with isopropyl
- Carbon 4: CH₂
- Carbon 5: CH₃
Final condensed structure:
CH₃CH=C(CH(CH₃)₂)CH₂CH₃
This is a linear representation, but it captures all atoms and their connectivity. Each segment shows how hydrogens are bonded compactly to carbon atoms. The central idea is to use parentheses to indicate branches or substituents like isopropyl groups.
