Solution: Given, [A]=0.1 mol L-1, [B]=0.2 mol L-1, k = 2.0×10-6 mol-2 L2 s-1Rate =k[A][B]2 = (2.0x 10-6 ) x (0.1 mol L-1) x (0.2 mol L-1) 2 = 8.0 x 10-9 mol-2 L2 s-1. The concentration of A is reduced to (0.1 – 0.06) = 0.04 mol L-1.Now according to the equation 1 mole of A reacts with 2 mole of B. So, 0.04 […]

Let x g of each gas is mixed. Molar mass of ethane = 30 g/mol Molar mass of hydrogen = 2 g/mol Mole = Given mass/Molar mass Moles of ethane = (x/30) mol Moles of hydrogen = (x/2) mol So, the fraction of total pressure exerted by hydrogen
Amine is a type of compound that is derived from ammonia, i.e., NH3. We can simply say, that amines are derivatives of ammonia. We study about amines in Organic Chemistry, and they are basically classified as functional groups or organic nitrogen compounds that contain a nitrogen atom with a lone pair. Generally, in amines, hydrogen

Thermodynamics is the study of flow of heat between system and surrounding. It deals with energy changes accompanying all types of physical and chemical processes. Thermodynamics helps to lay down the criteria for predicting feasibility or spontaneity of a process, including a chemical reaction, under a given set of conditions. It also helps to determine

Solution: Bond angle is inversely proportional to electronegativity of substituents. i.e., Electronegativity of side atom increase then the bond angle (X-P-X) decreases. So, X-P-X or F-P-F bond angle is least in POF3. That’s why the O-P-F is maximum. Hence, the correct order of bond angle for O-P-X in the given molecules
What is the correct order of bond angle for O-P-X in the given molecules? Read More »
Tip: To know the acidic character of haloform, we have to look for the stability of conjugate base What is acidic character? Acidic character is the ability to or a tendency to lose a proton and form a stable conjugate base. Factor acidic character depends Acidic character of the acid depends upon the stability of

What is acidic character? Acidic character is the ability to or a tendency to lose a proton. Carboxylic acid is highly acidic in nature. Factors responsible for acidic character (acidity) Inductive effect Mesomeric effect Hyperconjugation effect Ortho effect (especially for benzoic acid) Dependency of acidity on the above effects Acidity is directly proportional to -I, -M,
Arrange the following in acidic character Read More »
Pro Tip! Benzamide is less easily hydrolysed because of difference of positive charge density on carbonyl carbon. In hydrolysis reaction, hydroxyl ion (OH–) attacks on the carbonyl carbon, so we need to check out the positive charge density on carbonyl carbon. Solution We know that the nitrogen is less electronegative as compared to oxygen. So,
Benzamide is less easily hydrolysed than methyl benzoate. Why? Read More »
Bredt’s rule relates to bridge heads with carbon-carbon and carbon-nitrogen double bonds. This rule is first discussed by German Scholar Bredt’s in 1902. What is Bredt’s rule? According to this rule, a bridge head carbon atom of bicyclo compound cannot be sp2 hybridised or in other word a bridge head carbon atom cannot form double
