Question
Calculate the change in enthalpy for the following reaction
![The image shows a chemical reaction equation written on lined paper:
\[ \text{HO} \underline{\phantom{aa}} + \text{HBr} \rightarrow \text{Br} \underline{\phantom{aa}} + \text{H}_2\text{O} \]
This equation represents an organic substitution reaction where a hydroxyl group (OH) bonded to a carbon chain (represented by the wedge symbol) reacts with hydrobromic acid (HBr) to produce a bromo compound (Br attached to a carbon chain) and water (H₂O).
### Explanation:
- **HO:** Represents an alcohol group attached to a carbon chain.
- **+ HBr:** Addition of hydrobromic acid.
- **→:** Indicates a chemical reaction taking place, leading to the formation of products.
- **Br \(\underline{\phantom{aa}}\):** A bromine atom now attached to the carbon chain, replacing the OH group.
- **+ H₂O:** Water is produced as a byproduct.
This type of reaction is common in organic chemistry where alcohols are converted to alkyl halides using reagents like HBr. The wedges indicate the 3D orientation of the groups, which can be important for understanding stereochemistry in more complex molecules.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9991ebe6-d311-4747-8b3e-049d34946ced%2F148cdedc-3df5-472d-880a-5bc8a864fe73%2Fxlhmt6u_processed.jpeg&w=3840&q=75)

Expert Solution

Step 1: Define Lewis structure
Lewis structure is a method of representing bonding pattern in a molecule. It tells us how different atoms are connected in a molecule.
NOTE: Please note as bond enthalpy value is not provided, I have used standard value.If your question SPECIFICALLY asks you to use some particular value, please use that otherwise it will show INCORRECT solution.
