Which of the solutions have greatest osmotic pressure 30% sucrose 60% sucrose or 30% magnesium sulfate?
timofeeve [1]

Answer:Osmotic pressure is the minimum amount of pressure a solution must exert in order to prevent from crossing a barrier by osmosis. Solute molecules have difficulty crossing semipermeable membranes, so the more solutes that are in a solution, the higher the osmotic pressure will be. Between 30% sucrose and 60% sucrose, 60% sucrose will have a greater osmotic pressure than 30% because it has a higher percentage of solutes. However, since sucrose has a higher potential to cross semipermeable membranes and is more absorbable than magnesium sulfate, magnesium sulfate would have a higher osmotic pressure than 60% sucrose even though 60% sucrose has higher molecules.

What product is formed when benzene reacts with isobutyl chloride in the presence of AlCl3?
oee [108]

The product formed when benzene reacts with isobutyl chloride in the presence of AlCl3 is tertiary butyl benzene.

THE CHEMICAL REACTION AS

step 1 : CH₃ - CH - CH₂Cl +  AlCl₃  →  CH₃ - CH₂ -CH₂ - CH₂⁺ + AlCl⁻

step 2: CH₃ - CH₂ - CH₂ - CH₂⁺   ---H SHIFT--→  (CH₃)₃C⁺

PRODUCT

C₆H₆  + (CH₃)₃ C⁺  → C₆H₆ ( CH₃)₃ C⁺

Hence the product formed is tertiary butyl benzene.
