What is double bond equivalent with example?
As in simple words, the double bond equivalent is the number of double bonds and number of triple bonds present in organic molecules. For example, in the case of benzene, there are three double bonds and one ring so its double bond equivalent is four.
How is RDB calculated?
Saturated and Unsaturated Hydrocarbons So, the following simple rule could be suggested: for a molecule containing C carbon atoms, the number of hydrogens (H) plus the number of rings and double bonds (RDB) should be equal to 2C+2 in order to saturate all carbon valences.
What is the double bond equivalent value of the given compound?
A double bond equivalent for an organic compound can be calculated by the given formula. N = number of nitrogen atoms present in the given organic compound. There is no number of nitrogen and halogen atoms. Hence, the double bond equivalent for tetrahedron is 3.
What is double bond equivalent benzene?
The Double bond equivalent of benzene is 4. Double bond equivalent (DBE) is the calculation of the number of unsaturated bonds which is there in an organic compound. A molecule having a double bond or a ring is considered to be an Unsaturated molecule.
How to calculate the number of double bond equivalents?
This page allows you to calculate the number of double bond equivalents (DBE), or rings plus double bonds, and the hydrogen deficiency, Z, for an organic molecule.
What is the DBE value for triple bonds?
DBE Value 3 = three pie bonds or one triple bond + one double bond or three rings or two rings + one double bond or one ring + 2 double bonds
How many double bonds does c 4 h 7 no have?
A molecular formula of C 4 H 7 NO indicates two double bond equivalents. In other words, such a compound can have two double bonds, one triple bond, a double bond and a ring, or two rings. Alternatively, you can calculate double bond equivalents.
How to calculate double bond equivalents for a saturated hydrocarbon?
Alternatively, you can calculate double bond equivalents. For this, you need to keep in mind that a saturated hydrocarbon with n carbon atoms will have (2 n + 2) hydrogens. The presence of oxygen (s) doesn’t make any difference to the number of hydrogens. 2) minus the actual number of H atoms: 16 – 12 = 4 gives two double bond equivalents.
