Interpretation Introduction

Interpretation Empirical formula and molecular formula of the compound is to be determined.

Concept introduction:

Colligative properties: Properties of solutions which having influence on the concentration of the solute in it. Colligative properties are,

Decrease in the vapor pressure

Increase in the boiling point

Decline in the freezing point

Osmotic pressure

Osmotic pressure: The pressure created by the column of solution for the system at equilibrium is a measure of the osmotic pressure and is calculated by using the equation,

π = cRT

where,

c is the molar concentration

The number of moles of any substance can be determined using the equation

Number of mole =Given mass of the substanceMolar mass

Empirical formula: The simplest integer ratio of the element in a chemical formula. It can be obtained by reducing the ratio of elements to the simplest integer form of a molecular formula.

Order the following organic reactions by relative rate. That is, select '1' next to the reaction that will have the fastest initial rate, select '2' next to the reaction that will have the next fastest initial rate, and so on. If two reactions will have very similar initial rates, you can select the same number next to both. If a reaction will have zero or nearly zero initial rate, don't select a number and check the box in the table instead. Note: the "Nu" in these reactions means "a generic nucleophile." ملی CI :Nu 2 он 3 H Reaction Relative Rate (Choose one) ▼ Nu :CI: zero or nearly zero Nu :Nu bi (Choose one) zero or nearly zero : Nu لی Nu :H (Choose one) zero or nearly zero
