What is the structure of Decalin?

What is the structure of Decalin?

C10H18Decalin / Formula

Is Decalin optically active?

The trans form has a centre of symmetry, and is therefore optically inactive, whereas the cis form has no centre of symmetry in either of its two forms, and has non-superimposable mirror-images, so is optically active.

Is Decalin soluble in water?

LONDON–(BUSINESS WIRE)–Decalin (decahydronaphthalene) is clear colourless aromatic-scented liquid bicyclic organic chemical compound with the formula C10H18. The chemical is miscible with diethyl ether and chloroform, boundedly soluble in methanol and ethanol, slightly soluble in glacial acetic acid and practically …

What is cis-Decalin?

Cis-decalin rings flip in exactly the same manner as cyclohexane and at the same rate. The cis ring junction is highlighted by blue hydrogens. The ring inversion is caused by a conformational change. Back to stereochemistry home. 379.

Can you flip a decalin chair?

(b) trans-Decalin is a relatively rigid system and, unlike cyclohexane, the two rings cannot flip from one chair form to another.

Can you flip a decalin ring?

trans-Decalin Cannot Undergo Ring Flips: It Is Conformationally “Locked”

Is Decalin flammable?

FIRE HAZARDS * Decahydronaphthalene is a COMBUSTIBLE LIQUID. * Use dry chemical, CO2, water spray, alcohol or polymer foam extinguishers. * POISONOUS GASES ARE PRODUCED IN FIRE. * CONTAINERS MAY EXPLODE IN FIRE.

Is decalin aromatic?

This entity has been manually annotated by the ChEBI Team. Decalin (decahydronaphthalene, also known as bicyclo[4. 4.0]decane and sometimes decaline), a bicyclic organic compound, is an industrial solvent. A colorless liquid with an aromatic odor, it is used as a solvent for many resins or fuel additives.

Which type of decalin can flip?

So while cis-decalin can undergo ring flips, trans-decalin cannot.

Is Decalin aromatic?

Why is Equatorial more stable?

In the previous section, it was stated that the chair conformation in which the methyl group is equatorial is more stable because it minimizes steric repulsion, and thus the equilibrium favors the more stable conformer. This is true for all monosubstituted cyclohexanes.

Is decalin chiral?

In substituted cis-decalins, ring inversion takes place and the conformational equilibrium favours the side in which the substituent is equatorial, as illustrated with 1β-amino-cis-decalin and 2α-cis-decalol in Fig. 3.68B. Both cis- and trans-1-decalones are chiral and resolvable.

How many gauche interaction are there in cis decalin?

for cis-decalin (using cis-decalin 1 for the sake of discussion) clearly has 1,3-diaxial interactions (gauche butane interactions).
