Question

What is double bond equivalent formula?

Answer 1

Hello friend

 Formula of  Double Bond Equivalent (DBE) is = ∑n(v-2)/2+1

n=number of atom

v=valency of atom

EXAMPLE- C3H6O                     

DBE=3(4-2)+6(1-2)+1(2-2)/2+1    

=0+1           

=1                                

Hope it will help you

thanks,

Hey there,

Double bond equivalent=∑n(v-2)/2+1

n=number of atom
v=valency of atom

Eg-C₄H₆

DBE=4(4-2)+6(1-2)/2+1
=1+1
=2
