If bromobenzen polarity is 1.5D,then how many polarity of 2,3,5- bromobenzen?

Answer»

Answer:

In normal life we rarely come across pure substances.

Most of these are mixtures containing two or more pure

substances. Their utility or importance in life depends

on their composition. For example, the properties of

brass (mixture of copper and ZINC) are quite different

from those of German silver (mixture of copper, zinc

and nickel) or BRONZE (mixture of copper and tin);

1 part per million (ppm) of fluoride ions in water

prevents tooth decay, while 1.5 ppm causes the tooth

to become mottled and high concentrations of fluoride

ions can be poisonous (for example, SODIUM fluoride is

used in rat poison); intravenous injections are always

dissolved in water CON
