Draw the structure of the major organic product for each of the reactions below. You must show the correct stereochemistry of the product. The image shows three chemical reactions involving different starting compounds and reagents.### Reaction 1:- **Starting Compound**: The molecule is a cyclohexane ring with a bromine (Br) substituent.- **Reagents**: - Ethoxide ion (EtO⁻) - Ethanol (EtOH)- **Reaction Condition**: This setup suggests a nucleophilic substitution likely converting the bromine to an ethoxide group.### Reaction 2:- **Starting Compound**: A norbornane structure with a bromine (Br) substituent.- **Reagents**: - Hydrogen sulfide ion (HS⁻) - Tetrahydrofuran (THF) as the solvent- **Reaction Condition**: The reaction involves a nucleophilic substitution where the bromine is replaced, possibly by an SH group.### Reaction 3:- **Starting Compound**: A tert-butyl alcohol structure.- **Reagents**: - Phosphorus oxychloride (POCl₃) - Pyridine- **Reaction Condition**: These reagents suggest the transformation of the alcohol to an alkene through a dehydration reaction.Each reaction is illustrated with an arrow indicating the transformation facilitated by the given reagents, but the specific products are not depicted in the image. These reactions are typical in organic chemistry for demonstrating substitution and elimination processes.

Here, 1 reaction is favor the E2 Reaction, H and Br should have Antiperiplanar to each. So so 1 path is not favor, 2nd path is favor as mention image. 2, reaction is same of 1st, E2 reaction formed as alkene as major product is formed 3. Reaction is SN2 , inversion of configuration, POCl3 with Pyridine gives inversion of product.
