1. Criteria of spontaneity in terms of energy and entropy Tendency to attain state of minimum energy and maximum entropy. Energy decreasing [AH negative] and entropy increasing [AS positive] reactions are generally spontaneous. 2. Criteria of spontaneity in terms of free energy Te..

Consider two bodies A and B having masses and m 2 and initial velocities Uj and u 2 respectively. The bodies collide head on with each other and their collision lasts for t seconds (Fig. 2.16). Suppose the velocities of A an..

Cl 2 tube is proportional-to (1) vapour pressure of solvent (2) vapour pressure of solution (3) vapour pressure of solvent and solution (4) lowering of vapour pressure ^ 39. What is the relative lowering of vapour pressure when 12 g of urea is dissolved in 90 g of water (1) 0.02..

1. Explain different types of crystalline solids with example. 4 2. With a neat diagram, explain the structure of sodium chloride crystal. 4 3. Write a neat diagram, explain the structure of caesium chloride crystal. 4 4. Explain radius ratio with an exam..

The study of the boundary separating two bulk phases is called surface chemistry. This boundary is also known as boundary surface or interface. It is expressed either by a hyphen or a straight vertical line. viz. solid-liquid or solid/liquid indicates the interface between ..

CHEMICAL PROPERTIES OF ACETYLENES ADDITION REACTIONS AT THE TRIPLE BOND Nucleophilic electrons of alkynes add H 2 and electrophiles in reactions similar to additions to alkenes. Alkynes can add one or two moles of reagent but are less reactive (except to H 2..

1. Isomerism Structural and Stereo. Structural isomerism (i) Ionization Ex. [Co(NH3)5S04]Br and [Co(NH3)5Br]S04 redviolet red (ii) Linkage isomerism Ex. [Co(NH3)5N02]Cl2 and [Co(NH3)5ONO]Cl yellow red (iii) Hydrate isomerism Ex [Cr(H20)6]Cl3, [Cr(H20)5Cl]Cl2.H20 and ..

This unit deals with some important features of surface chemistry such as adsorption, catalysis, colloids, emulsions etc. The term surface or interface as interpreted in surface chemistry refers to a region where two phases meet. Most of the physical and chemica..

Example:1 Although cyclopropanes are less reactive than alkenes, they undergo similar addition reactions. (a) Account for this by geometry and orbital overlap. (b) How does HBr addition to 1,l-dimethylcyclopropane resemble Markovnikov addition? Answer: (a) Because of the ring strain in ..

1. Classification based on functional group 2. Nomenclature Some common names are methane, ethane, propane, butane. Beyond butane, indicated by the number of carbons. Ex. decane (10 carbon atoms) IUPAC system (i) Longest carbon chain is parent chain, (ii) Parent chain is number..
