NCERT Solutions for Class 12 Chemistry Chapter 7: Points to Remember
Students can refer to the important points related to Class 12 Chemistry chapter 7 as mentioned below:
Group 15 elements (Nitrogen Family): (i) Elements: N, P, As, Sb & Bi (ii) Electronic configuration: ns2np3 (iii) Oxidation state: +3+3 and +5. +3+5. +3 oxidation state is favoured by heavier elements due to ‘inert pair effect’.
Nitrogen forms oxides in various oxidation states: N2O, NO, N2O3, NO2, N2O4 and N2O5. These oxides have resonating structures and have multiple bonds.
Ammonia can be prepared on large scale by Haber’s process
HNO3 is a strong monobasic acid and is a powerful oxidising agent. Metals and non-metals react with HNO3 under different conditions to give NONO or NO2
Phosphorus forms a number of oxoacids. Depending upon the number of P–OHP–OH groups, their basicity varies. The oxoacids which have P–HP–H bonds are good reducing agents.
Group 16 elements (Oxygen Family – Chalcogens) (i) Elements: O, S, Se, Te, Po (ii) Electronic configuration: ns2np4 (iii) Maximum oxidation state of +6+6.
Sulphur combines with oxygen to give oxides such as SO2SO2 and SO3SO3. SO2SO2 is prepared by the reaction of sulphur with oxygen. It is used in the manufacture of H2SO4H2SO4.
Group 17 elements (Halogens) (i) Elements: F, Cl, Br, I, At (ii) Electronic configuration: ns2np5 (iii) The common oxidation state of these elements is –1. However, highest oxidation state can be +7
Group 18 elements (Nobles gases or inert gases) (i) Elements: He, Ne, Ar, Kr, Xe, Rn (ii) Electronic configuration: ns2np6ns2np6 except He which has configuration of 1s21s2. (iii) All the noble gases except RnRn occur in atmosphere.
