Assertion (A) : Non-stoichiometric compounds are called Bertholide compounds. NaCl and KCl crystal, when heated in an atmosphere of Na and K varpours, respectively, they impart violet and yellow colours to NaCl and KCl , respectively. Reason (R ) : Metal excess defect is due to the presence of extra cations atg the interstitial sites. The excess metal ions move to the interstitial sites and the electrons to the neighbouring sites. The colour results byt the excitation of these electrons by absorbing suitable energy from visible light. When the excited electroon comes back to the ground state, there is emission of radiation in the visible region and gives complimentary colour.

Assertion : In ZnO, the excess Zn^(2+) ions are present in interstitial sites. Reason : Metal excess crystals have either missing cation or anion in interstitial site.

Assertion (A) : MgCl_(2) is an ionic compound . Reason (R ) : Metals and not -metals react by mutual complete transfer of electrons .

Assertion (A) : Mercurous ion is paramagnetic. Reason (R ): It contains one unpaired electron.

Assertion (A) : Fe^(3+) (g) ion is more stable than Fe^(2+)(g) ion. Reason (R) : Fe^(3+) ion has more number of unpaired electrons than Fe^(2+) ion.
