The most stable conformer of glucose has to be drawn. Concept introduction: Conformers: The different spatial arrangements of the atoms the result from rotation about a single bond is called conformational isomers. Stereoisomerism (or) geometric isomerism: It is known as cis-trans isomerism or E-Z isomerism is a form of stereoisomerism the each of two or more chemical compounds having the same molecular formula but a different geometric arrangement; an unsaturated compound or ring compound in which rotation around a carbon bond is restricted, as in ( cis ) and ( trans ) configurations know as geometric isomerism. Relative stability of cyclohexane: The most stable conformation of cyclohexane is the chair shown to the right, the respective carbon (-C-C-) bonds are it close to (109 .5 ° ) , it is almost free of angle strain, it is also a fully staggered conformation and so is free of torsional strain. So the chair conformation is the most stable conformation.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule
