What are molecular orbitals? How are they formed?What does molecular orbital theory states? what is the significance of molecular orbital theory?Ans) Molecular orbitals are formed when atomic orbitals of equal energy hybrize. MOT states that n no. of atomic orbitals hybridise to form n no. of molecular orbitals of equal energy. This theory helps us to give the arrangement of electrons in molecules and also its magnetic properties.
what is the name given to the impure copper obtained through this process
Ionic bonds are usually formed by combination of elements with: (1) High ionisation potential and low electron affinity (2) Low ionisation potential and high electron affini
Carboxylic group,amino group,ester group,amide group group are key functional groups in aspartame although phenol is present it is not a functional group.
Carbon has maximum catenation ability. The self-linkage of the atoms of elements to make long chains is known as catenation.
how to express nernst equation by daniel cell? as we have taken mass of subsstance insted of concentration
(a) Co-ordination compound A co-ordination compound contains a central metal atom or cation which is surrounded by a suitable number of anions or neutral molecules and usually re
Enthalpy, H, is defined by the relationship H=U+pV. The enthalpy change, ΔH, for finite changes at constant pressure is given by the expression ΔH = ΔU+pΔV, so making the enthalpy
