What is the condensed formula for 6-chloro-2-methyl-3-heptyne?

The condensed formula for 6-chloro-2-methyl-3-heptyne is C9H15Cl.

To determine the condensed formula for 6-chloro-2-methyl-3-heptyne, we should first break down the name into its individual components.

- Prefix: "6-chloro" indicates that there is a chlorine atom attached to the sixth carbon atom of the parent chain.
- Substituent: "2-methyl" means that there is a methyl group attached to the second carbon atom of the parent chain.
- Parent chain: "3-heptyne" tells us that the parent chain is a heptyne (a carbon chain with seven carbon atoms) and the triple bond is located on the third carbon.

Now let's construct the condensed formula step by step:

1. Start with a seven-carbon chain (heptyne).
CH₃CH₂CH ≡ CHCH₂CH₂CH₃

2. Add a chlorine atom to the sixth carbon atom:
CH₃CH₂CH ≡ CHCH(Cl)CH₂CH₃

3. Attach a methyl group to the second carbon atom:
CH₃C(CH₃)CH₂CH ≡ CHCH(Cl)CH₂CH₃

Therefore, the condensed formula for 6-chloro-2-methyl-3-heptyne is CH₃C(CH₃)CH₂CH≡CHCH(Cl)CH₂CH₃.

This is easier if you draw it out. You go left to right on the carbon chain. Branches off of the main carbon chain can be indicated with a parentheses.

example: propan-2-ol condensed formula can be CH3CH(OH)CH3.
Dont forget the triple bond for your heptyne.
