A hydrocarbon (X) has the molecular formula C_8H_10 . It does not decolourise bromine water and is oxidised to benzoic acid on heating with K_2Cr_2O_7/c.H_2SO_4 . It can also have three other isomers A, B and C. Write the structures of X, A, B and C.

An organic compound A (molecular formula C_2H_4O) on reaction with excess formaldehyde in presence of Ca(OH)_2 provides B (molecular formula C_4H_(12)O_4) . A on reaction with AI(Oet)_3 gives C (molecular formula C_4H_8O_2) .Both A and C on treatment with LiAIH_4 in dry ether furnish the same compound D (molecular) formula C_2H_6O ). A on reaction with ammoniacal AgNO_3 gives E (molecular formula C_2H_7NO_2 ). Reaction of A with D in presenece of dry HCI provides F (molecular formula C_6H_(14)O_2 ). Write down the structures of A to F along with the arrow head equation for the above reactions.

The well know mineral flourite is chemically calcium fluoride. It is a well known fact that in one unit cell of this mineral, there are four Ca^(2+) ions and eight F^(-) ions and Ca^(2+) ions are arranged in f.c.c. lattice. The F^(-) ions fill all the tetrahedral holes in the face centred cubic lattice of Ca^(2+) ions. The edge length of the unit cell is 5.46xx10^(-8) cm. The density of the solid is 3.18"g cm"^(-3) . Use this information to calculate Avogadro's number (Molar mass of CaF_(2)=78.0"g mol"^(-1) )

H, He^(+), Li^(2+) are examples of atoms or ions with one electron each . The energy of such atoms when in the n-th energy state (according to Bohr,s theory , n=1,2,3…. =principal quantum number ) is E_n =(-13.6 Z^2)/(n^2) eV (1 eV =1.6xx10^(-19)J) . For the ground state ,n=1 . in order to raise the atom from the ground state to n=f , the suitable incident light should have a wavelength given by lambda=(hc)/(E_f-E_1) . But the atom cannot stay permanently in the f-energy state, ultimately , it comes to the ground state by radiating the extra energy , E_f-E_1 as electromagnetic radiation . The electron of the atom comes from n=f to n=1 in one or more steps using the permitted energy levels . As a result there is a possibility of emission of radiation with more than one wavelength from the atom. Planck's constant =6.63 xx10^(-34)J*s and velocity of light c=3xx10^(8)m*s^(-1) . The wavelength of radiation emitted for the transition of the electron of He^+ ion from n=4 to n=2 is
