Pyridine like benzene, has six pi -electrons in delocalized pi -orbitals, but unlike benzene the orbitals will be deformed as electrons are more attracted towards the nitrogen atom because of its high electro negativity. This is reflected in the dipole of pyridine which has the negative end on N and the positive end on the nucleus. We can compare the respective properties of benzene, pyridine, pyrrole, furan and thiophene, which very frequently give aromatic electrophilic and nucleophilic substitution reactions in different positions. Which of the following compounds are aromatic.

Group 13 of periodic table consists of boron or aluminium family. Boron being the first member, shows anomalous behaviour due to its small size and high nuclear charge/size ratiom high electrone gastivity and non availability of d-electrons. All the group 13 members forms hydrides, hydroxides, halides showing +3 covalency, however boron forms electron deficient species. Which of the following statement(s) is/are correct. (I) Both B and Al forms anionic hydrides (II) Both form alkaline hydroxide of formula M(OH)_(3) (III) Both B and Al forms a series of polymeric hydrides (IV) Both forms monoeric halides MX_(3)

Monosaccharides and disaccharides in which aldehyde group is free reduce Tollen's reagent as well as Fehling solution and hence are known as reducing sugars. Carbohydrates react with excess of phcayl kydrazine to yield their crystalline derivatives called oxazones. In osazone formation only the first two carbon atoms are irrelved Osazone on hydrolysis gives same which are reduction with ZnCH_(3)COOH gives a ketose sugar Osazone cannot be formed by whihc of the following

If not, give examples of elements which do not obey Ohm's law. (c ) A low voltage suply from which one needs high currents must have very low internal resistance.Why (d) A high tension (HT) supply of say, 6kV must have a very large internal resistance, Why ?
