The fate of the world if the hydrogen bonding becomes very weak and the boiling point of water falls to − 60.7 ° C is to be determined. Concept Introduction: One of the important intermolecular forces present in the polar molecules is the hydrogen bonding force. Hydrogen bonding is observed for molecules having hydrogen atom covalently bonded to a more electronegative atom such as nitrogen or oxygen or fluorine and another molecule having an unshared pair of electron on nitrogen or oxygen or fluorine atom. Hydrogen bonding is stronger than the London dispersion force and the dipole-dipole force. The boiling point of a liquid is the temperature at which the vapor pressure of that liquid becomes equal to the surrounding pressure. At the boiling point, the liquid changes its state to vapor. The boiling point of a substance depends on the intermolecular forces present in the liquid state of that substance. The stronger the intermolecular forces, the higher is the boiling point of the liquid.

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...]
