The enol carbon or ∝-carbon nucleophile attacks at molecular bromine in the acid-catalyzed α-bromination of a ketone
Treatment of ketones with bromine in the presence of acid will results in formation of a new C-Br bond at the alpha position. The purpose of the acid is to catalysed formation of the enol from ketone , which is active nucleophile in the reaction. This reaction is called haloform reaction which is used to identify the methyl substituted ketone in the presence of aldehyde.

La respuesta está en el enunciado
Explanation:
Una solución química es definida como una mezcla de dos o más sustancias donde, la que está en mayor proporción, es definida como el solvente y los componentes que están en menor cantidad se definen como los solutos.
En general, en la formulación de bebidas, el solvente es agua, los solutos son otros componentes como saborizantes y colorantes que permiten que el consumidor tenga experiencias agradables con la bebida.
Además, la solución debe ser homogenea, esto es, todos los solutos se encuentran completamente disueltos en el solvente. Una bebida comercial a la que se le encuentren partículas no genera confianza y puede ser rechazada por parte del consumidos.
Answer:
0.6257 M is the molarity of solution that is 5.50 percentage by mass oxalic acid.
Explanation:
Mass percentage of oxalic acid = 5.50%
This means that in 100 grams of solution there are 5.50 grams of oxalic acid.
Mass of solution , m = 100
Volume of the solution = V
Density of the solution = d = 1.024 g/mL
V = 97.66 mL = 0.09766 L
(1 mL = 0.001 L)
Moles of oxalic acid =
The molarity of the solution :
0.6257 M is the molarity of solution that is 5.50 percentage by mass oxalic acid.
