chair form

The values of the above quantities are consistent with a chair form structure.

Maybe one might say that it is more difficult to accommodate the easy chair form in American furniture."

The referendum would have asked voters if they would support changing to an elected chair form of government.

For the same reasons, the actual boat forms have slightly higher energy than the chair forms.

This chair form was particularly popular in England and found primarily in upper class homes.

The quinic ring adopts an almost perfect chair form.

Cyclohexane (chair form) Follow the link if you need help on controlling the molecule display.

It was now their job to glyph Narciso Rodriguez in chair form.

The values of these parameters show that the observed spectrum is due to the chair form with an equatorial methyl group.

The presence of other conformers, in addition to the chair form, was indicated from bands in the spectra.

It's extremely unstable in chair form (and also in step-ladder form actually) but it'll have to do.

However, due to interactions between the hydrogen atoms, the angles and bond lengths of the actual chair forms are slightly different from the nominal values.

It is suggested that severe steric interactions in the chair form force it to adopt this unusual conformation.

These are the C and C chair forms and an additional S skew-boat conformation.

The sulfur ring in cyclo-S has a "chair" conformation, reminiscent of the chair form of cyclohexane.

The dimeric form has been isolated in a low temperature argon matrix and vibrational spectra indicate that it has a centrosymmetric chair form.

Conformations with 1,3 diaxial interactions are usually disfavored due to steric congestion and can shift equilibrium to the other chair form (example: C to C).

As well, in the most stable chair form of cyclohexane, axial hydrogens on adjacent carbon atoms are pointed in opposite directions, virtually eliminating eclipsing strain.

The boat conformation represents the energy maximum on a conformational itinerary between the two equivalent chair forms; however, it does not represent the transition state for this process, because there are lower-energy pathways.

In each case, the N,N′-dioxide molecule occupies a site of symmetry . The piperazine ring takes the chair form, with two N—O bonds oriented axially in a trans configuration.

He clearly understood that these forms had two positions for the hydrogens (again, to use modern terminology, axial and equatorial), that two chairs would probably interconvert, and even how certain substituents might favor one of the chair forms.

The slower rate of solvolysis in the six-membered ring system may be due to an extra activation energy contribution caused by the conversion of a neutral chair form to the twist boat or half chair conformation, prior to the actual solvolysis.

Similar studies of the 7a-ethyl-homologue showed that the ethyl bicycic ketol existed in a cis conformation in which the 7a-ethyl group is equatorially oriented and the hydroxyl group is axially oriented in the chair form of the six-membered ring as shown above.

Weak dielectric absorption associated with reorientation of nondipolar D molecules is attributed mainly to the induction of a total dipole moment of ∼0.2 D in the 28 water molecules of the large structure II cage by two equal and opposed dipoles in the chair form of D.

The reason for the present preference for the formation of trans-dihydrophenanthrene rather than cis-dihydrophenanthrene as the intermediate might be attributable to the more stable chair form transition state than boat one and the conformational fixation to the chair form in the ground and transition state is possible in the anti-conformer.
