Calculate the double bond equivalent of benzens from its molecular formula.

Write D.B.E (Double bond equivalent) for the following compound: [Write answer of part (a),(b),(c) and (d) in the same order and present the four digit number as answer in OMR sheet. For example.]

Double bond equivalents help in search for structure of a compound. It involves following steps: Calculate the expected number of hydrogen atoms in the saturated structure. (a) For C_(n) there would be: (2n+2) hydrogens if compound contains C,H,O only. (b) For C_(n),N_(m) there would be (2n+2+m) hydrogens. Subtract the actual number of hydrogen and divide by 2. This gives the double bond equivalents. Ring is considered to possess single DBE. Double bond equivalent of benzene will be:
