The oxidation number of carbon in C_(12) H_(22) O_(11) is

In an auto engine having no pollution control device 5% of the fuel (C_(8)H_(18)) is left unburnt. Molar ratio under same P and T of CO and C_(8)H_(18) emitted in exhaust gas is .

Answer the following : (i) What would be the molecular formula for a straight chain hydrocarbon having 8 carbon atoms with (a) all C-C single bond, (b) Three C-C double bond, (c ) one C-C triple bond and one C-C double bond. (ii) What is the minimum number of carbon atoms in (a) a branched alkane, (b) cyclo-alkane

Write the structure and give IUPAC systematic name of an alkane or cycloalkane with the formula : (a) C_(8)H_(18) that has only primary hydrogen atoms (b) C_(6)H_(12) that has only secondary hydrogen atoms.

i. 27.8gm mixture of alkyne and alkane (both containing same number of carbon atoms) is dissolved in 1000gm of benzene. The solution freezes at 2.45^@C (lower than that of benzene). Another 27.8gm mixture requires 0.6 mol of H_2 for complete hydrogenation. Calculate the chemical formula of alkyne and alkane ( K_f for C_6H_6=4.9 ). ii. Alkyne on hydrogenation with H_2+Pt gives the same alkane. Alkyne does not react with ammoniacal AgNO_3 solution. Give the structures of both alkyne and alkane.
