Compound b has a molecular formula of c7h16o. what is the unsaturation number (un) or double-bond equivalent (dbe)?

aksik [14]

Answer: -

Zero

Explanation: -

Double bond equivalent or level of unsaturation is the number of unsaturation present in a organic molecule. The term unsaturation may refer to a double bond or a ring system.

The double bond equivalent for an organic compound can be found out by the help of the formula

DBE = C+1 -0.5 H - 0.5 X + 0.5 N

The chemical formula of the compound B = C₇H₁₆O

So there are 7 carbons, 16 hydrogens and 1 oxygen. There is no halogen or nitrogen.

Plugging into the formula,

DBE = 7 + 1 - 0.5 x 16

= 0

Thus there is no unsaturation or double bond present in the compound B with the molecular formula C₇H₁₆O
