Lithium forms monoxide only when heated in oxygen. Sodium forms monoxide and peroxide in excess of oxygen. Other alkali metals form superoxide with oxygen i.e MO_(2) . The abnormal behaviour of lithium is due to small size. The larger size of nearer alkali metals also decides the role in formation of superoxides. The three ions are related to each other as follows O^(2-) overset(1/2O_(2))rarrunderset(O_(2^(2-)))overset(O_(2))rarrunderset("superoxide ion")2O_(2) Lithium does not form stable peroxide because

Emulsions are normally prepared by shaking the two components together vigorously although some kind of emulsifying agent usually has to added to stabilize the product. This emulsifying agent may be a soap or other surfactant (surface active) species or a lyophilic sol. Emulsions are broadly classified into two types : (i) Oil in water emulsions (O/W): Oil acts as dispersed phase and water acts as dispersion medium (ii) Water in oil emulsions (W/O) : Water acts as dispersed phase and oil acts as dispersion medium. Dye test, dilution test may be employed for identification of emulsions. Read the two statements : A) Milk is an example of oil in water (O/W) type emulsion B) Cold cream is an example of water in oil (W/O) type emulsion

Observe the following a and b statements. All the family members have identical characters. Differences in character within very closely related groups of organisms are referred to as variation.

Electrophilic substitution on mono substituted benzene is determined by electronic effects +1, -M groups are ortho, para directors, where as -1,-M groups are meta directions. When there is a competition between inductive and mesomeric effects, the latter wins over. Electrophilic substitution on disubstituted benzene is determined by the combined effect of both groups. Usually activating group wins over deactivating group. When one of the groups has a lone pair of electrons, that will determine the product formation. Usually a third group will not enter the position in between the two existing groups due to steric reasons. Identify the incorrect statement
