Compound X of molecular formula C4H6 takes up one equivalent of hydrogen in presence of Pt to form another compound Y which on ozonolysis gives only ethanoic acid.The compound X can be

  • Solution

  • Solution

An organic compound ‘X’ – (molecular formula C6H7O2N)has six atoms in a ring system, two double bonds and a nitro group as substituent; ‘X’ is:

  • Solution

    The compound has –NO2 group, so N is not present in ring and the six membered ring has C atoms only, so it should be homocyclic. Further the six-membered cyclic compound has only two double bonds, it is not aromatic(for aromaticity six membered cyclic compound should have three alternate double bonds).

The molecular formula of a compound in which double bond is present between C & C :

  • Solution

    Double bond in between carbon-carbon is present in alkenes whose general formula is CnH2n.

After ozonolysis of benzene(not hydrolysis), the product is

  • Solution

Aromatic compounds burn with sooty flame because

  • Solution

    They have a relatively high percentage of carbon.

Benzene can be obtained in the reaction

  • Solution

Toluene on treatment with CrO3 and (CH3CO)2O followed by hydrolysis with dil HCl gives

  • Solution

Benzene can react with :

  • Solution

\(C_{3}H_{8} + Cl_{2} \overset{light}{\rightarrow} C_{3}H_{7}Cl + HCl\) is an example of which of the following type of reactions?
