Answer :
Regarding the specific question of which step is made easier through the application of ultrasonic waves in the experimental procedure, the answer is the Preparation of the Grignard reagent.
In the experimental procedure, the step made easier through the application of ultrasonic waves is the preparation of the Grignard reagent. Ultrasonic waves can help in the formation of the reagent by providing energy and agitation to promote the reaction between the magnesium and the organic halide.
Ultrasonic waves can be used to speed up the process of preparing Grignard reagents by improving the dispersion of the magnesium in the solvent. This allows for more efficient reactions and higher yields of the desired product. Therefore, the application of ultrasonic waves makes the preparation of the Grignard reagent step easier in the experimental procedure.
