Chapter 18, Problem 9ASA
Interpretation Introduction
Interpretation:
The reagents used and the corresponding reaction for the preparation of hydrogen sulfide
Concept introduction:
The elements that have low conductivity (thermal and electrical) and brittle in nature are known as non-metals. Compounds containing nonmetallic atoms are generally bonded by a covalent bond. The nonmetallic compounds are prepared by simple reactions in the laboratory.

Draw the condensed structure of the organic molecule that produces sodium propanoate when reacted with NaOH.
Correct each molecule in the drawing area below so that it has the structure it would have if it were dissolved in a 0.1 M aqueous solution of NaOH.
If there are no changes to be made, check the No changes box under the drawing area.

Br-Br
H3CO
The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form the final product. In cases that involve a
negatively charged nucleophile, the attack of the nucleophile leads directly to the product.
