Carboxylate salts
Carboxylate salts are less reactive than esters in nucleophilic acyl substitution reactions for two reasons. First, resonance stabilization of carboxylate salts is particularly significant because carboxylates have two identical, significant resonance structures;
Dipole Moment - Applications of Hyperconjugation As hyperconjugation affects the development of charges, it as well affects the dipole moment in the molecule. The increase in d
what is electrovalent bond
Bond strength in hydrocarbons As much shorter is the bond size, the greater is the compression among molecules atomic nuclei and therefore greater is the strength of that bond.
Discuss "cohesive energy" and "electron affinity". ‘Cohesive energy’: In a chemical bond, it’s the energy required to dissociate a solid into isolated atoms or molecules as ap
WHAT IS THE MEANING OFPotential Energy Surfaces
A moving particle may have wave motion, if: (1) Its mass is very high (2) Its velocity is negligible (3) Its mass is negligible (4) Its mass is very high and velocity
Trace and ultratrace analysis: The accuracy, precision and detection limits of flame AAS depend on how the analyte sample is introduced into the atomiser. We need to transfer
For an electron if the uncertainty in velocity is Δ v , the uncertainty in its position( Δ x ) is given by: (1) hm/ 4 Π Δ b (2) 4 Π / hm Π v
Q. Show the chemical properties of Uranium? Uranium is mainly extracted from pitchblende. The concentrated ore (pitchblende, U 3 O 8 ) is washed and then fused with sodium nitr
Mention the major reason for the anomalous behaviour of lithium in Group of the periodic table. Why is the third ionization energy of manganese (At. No. =25) unexpectedly high?
