The given compound is a hemiacetal or not has to be indicated. Concept Introduction: Aldehydes contain a carbonyl group that is bonded to a hydrogen atom and a carbon atom. Ketones are compounds that contain a carbonyl group bonded to two carbon atoms. Aldehydes and ketones undergo addition reaction across the carbonyl group. Aldehydes and ketones react with alcohol to form hemiacetal as the product. This reacts with further molecule of aldehyde or ketone to form acetal. Hemiacetal is a addition product that is obtained by reaction between aldehyde or ketone with alcohol. The general reaction of hemiacetal formation can be given as, From the above general structure of hemiacetal it is found that it is an organic compound that contains a carbon atom that is bonded to an alkoxy group and a hydroxyl group.

Question

It is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO interacting with anti-bonding MO...]

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
