The unshared pair of electrons on a cyanide ion can act as

SO_2 can act as

Assertion : Cyanides R - C -= N : are very much weaker bases than aliphatic bases. Reason : This is due to the fact that as the nitrogen atom becomes more multiply bonded, the lone pair of electrons are accommodated in an orbital that has more 'S' character. The electron pair is thus drawn closer to the nitrogen nucleus, and held more lightly by it.

In which of the following compounds is there the least delocalization of the lone pair of electrons on the nirtogen atom?

In 'NO3' ion,the number of bond pairs and lone pairs of electrons on nitrogen atom are

Write the number of bond pairs of electrons and lone pairs of electrons in electron dot structure of ammonia molecule.

The hexaaquamanganese(II)ion contains five unpaired electrons,while the hexacyano ion contains only one unpaired electron.Explain using crystal field theory.

The Valence Shell Electron pair Repulsion (VSEPR) theory helps in predicting the shapes of covalent molecules. Arrange the bond pair electron and ione pair electron in the decreasing order of the replusive interactions among them.

Explain the bond pair electrons and lone pair electrons of H_2O and NH_3 molecules with suitable drawing.
