### How many degrees of unsaturation does the compound C5H10 have?

The DU for C5H10 is [(2(5) 2) 10]/2 1. Therefore, this compound must have one double bond or one ring. Any compound that has five C’s and one double bond or one ring will fit the formula.

### How many signals are in acetyl acetone in enol form?

On this basis chemical shifts for the five signals are given in Table I to the nearest cycle at 40 Mc./s. TABLE I CHEMICAL SHIFTS IN PURE ACETYLACETONE AT 40 Mc./s.

**Why is acetyl acetone bidentate ligand?**

Acetylacetonate ion contains two O atoms which allow this ligand to function as a bidentate ligand.

**What is ACAC ligand?**

Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH. 3COCHCOCH − 3) and metal ions, usually transition metals. The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring.

#### How do you calculate degrees of unsaturation?

To find the degrees of unsaturation:

- Count the number of carbon, hydrogen, nitrogen, and halogen atoms present in the compound.
- Double the number of carbons and from this number subtract the number of hydrogens and halogens.
- Add 2 plus the number of nitrogens to the resultant.
- Divide the new number by two.

#### What is the formula for calculating degree of unsaturation?

Calculating The Degree of Unsaturation (DU) [2C+2=(2×3)+2=8.] The compound needs 4 more hydrogens in order to be fully saturated (expected number of hydrogens-observed number of hydrogens=8-4=4). Degrees of unsaturation is equal to 2, or half the number of hydrogens the molecule needs to be classified as saturated.

**Why enol form of Ethylacetoacetate is more stable than keto form explain with structure?**

Resonance and hydrogen bonding increases enol content. Enolic form of phenol is more stable than keto form by -13 kcal/mole of energy hence phenol exist exclusively as an enol. Enolic tautomer is less polar due to intramolecular hydrogen bonds than the corresponding keto form.
