Hello young chemists! Ever wondered how those halogenoalkanes get their fancy names? Let's dive right in! And remember, chemistry isn't just about beakers and labs, it's everywhere! 🌍💡

The position of the halogen is determined by a locant on the main carbon chain.

• 📖 Think of locants as apartment numbers in a building. Just like you’d need to know which apartment (or "locant") your friend lives in to visit them, molecules use locants to indicate where a particular atom or group resides.

(Now, Table 11 wasn't given, but imagine a fancy table that lists halogens and their prefixes. Something like this:)

• F (Fluorine) ➡️ Fluoro
• Cl (Chlorine) ➡️ Chloro
• Br (Bromine) ➡️ Bromo
• I (Iodine) ➡️ Iodo
   
• 🌍 Real-World Example: Ever had salt (NaCl) on your fries? The 'Cl' in it stands for Chlorine. So, Chlorine isn't just in pools but also in your snacks!

If methane or ethane has just one halogen, the locant isn't mentioned because it's the same wherever you place it.

• For instance: A molecule with one bromine on ethane is simply "bromoethane", NOT "1-bromoethane".
• 🍔 Think of it like ordering a cheeseburger. If you ask for a burger with just cheese, they won't ask where you want the cheese. It's always on top of the patty!
