<h3>Answer:</h3>

                    It is fat-soluble

<h3>Explanation:</h3>

                         The cheeseburger grease adhered to cloths can not be washed by simple rinsing it with water. This is because of the fact that "<em>Like Dissolves Like</em>". As grease is non-polar in nature therefore it will show no interaction with water because water is polar in nature. Hence, in order to make interactions of grease we must add some sort of non polar solvent like Tetrachloroethylene (C₂Cl₄). Now, both being non-polar in nature will interact, make attractions and grease will happily leave with Tetrachloroethylene leaving the cloth clean again.

<h3>Remember:</h3>

                   Tetrachloroethylene is non polar because the four chlorine atoms about the double bond cancel out each others effect making the dipole moment zero hence, the overall molecule becomes non-polar.

The organic compounds that are divided into two types, simple and complex, are called _____.
Sati [7]

The organic compounds that are divided into two types, simple and complex, are called carbohydrates.

Carbohydrates are diveded into twy types: simple and complex (starches, fiber, glycogen).

Simple carbohydrates are made of one (monosaccaharides) or two sugar units.

Complex carbohydrates are made up of many sugar units.

For example, glucose (C₆H₁₂O₆) is a simple carbohydrate.

Glucose is chemical compound composed of six carbon atoms, twelve hydrogen atoms and six oxygen atoms.

Starch is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.

Explain why the C―Ha bond is much more acidic than the C―Hb bond in pentan-2-one. Select the single best answer. 253 Ha is less
mafiozo [28]

Answer:

Ha is more acidic than Hb because loss of Ha forms a resonance-stabilized conjugate base.

Explanation:

The carbon atom that is next to the carbonyl group in pentan-2-one is known as the alpha carbon atom, this carbon atom bears the Ha, the alpha hydrogen atoms.

Ha is more acidic than Hb because, loss of Ha leads to the formation of a resonance stabilized enolate ion. This resonance stabilization of the ion formed makes loss of Ha an easier process than loss of Hb, hence the answer above.

What is the name of the ionic compound AlBr3?
Aleksandr [31]

Answer: Correct name will be is aluminum bromide

Explanation:

In a molecular formula ,AlBr_3

Aluminium atoms present = 1  

Bromine atoms present = 3

Charge on aluminium is +3 and charge on bromine is -1.

While naming:

  • Name of the cation is written first. Simple name of the element is written
  • After name of cation name of an anions written with suffix 'ide' in the end.

So, the name of AlBr_3 will be aluminium bromide.
