Thus, ethylene glycol and water molecules can form hydrogen bonds to each other, just as the individual molecules can, which means that they mix freely, in all proportions, as shown in the diagram below.

H2 is molecular hydrogen.it is a molecule of hydrogen that consists of two hydrogen atoms bonded together by one single bond. 2H denotes two moles of elemental hydrogen.it should be noted that elemental hydrogen is not bonded to anything.

Polar protic solvents are capable of hydrogen bonding because they contain at least one hydrogen atom connected directly to an electronegative atom (such as O-H or N-H bonds). ... Polar aprotic solvents contain no hydrogen atoms connected directly to an electronegative atom and they are not capable of hydrogen bonding.

Hydrogen bonding of water molecules Thanks to their polarity, water molecules happily attract each other. ... These attractions are an example of hydrogen bonds, weak interactions that form between a hydrogen with a partial positive charge and a more electronegative atom, such as oxygen.

the NH3 can form four Hydrogen Bonds too,theoretically. Because the NH3 has one lone pair and three N-H bonds, it can be hydrogen donor and the accepter.

Carboxylic acids are polar. Because they are both hydrogen-bond acceptors (the carbonyl –C=O) and hydrogen-bond donors (the hydroxyl –OH), they also participate in hydrogen bonding. Together, the hydroxyl and carbonyl group form the functional group carboxyl.

The hydroxide ion (OH-) is a very good acceptor of hydrogen bonds, with the first water molecule binding strongly to form H3O2- (right, where the proton is off-center, giving rise to a low-barrier hydrogen bond) hydrated ions.

Originally Answered: Which molecules can hydrogen bond? Hydrogen bond is formed only by the three highly electronegative elements- fluorine, oxygen and nitrogen. So, hydrogen bonding is possible only in those compounds in which the hydrogen atom is directly bonded to fluorine, oxygen or nitrogen.

The hydroxyl group (—OH) is found in the alcohol and phenol functional groups. (Note: that's not the same as hydroxide, OH-, which is ionic.) – in alcohols, a hydroxyl group is connected to a carbon atom. – in phenols, —OH is connected to a benzene ring.

The Energy Associated with a Chemical Bond The higher the bond energy, the 'stronger' we say the bond is between the two atoms, and the distance between them (bond length) is smaller. For instance, the HO-H bond in a water molecule requires 493 kJ/mol to break and generate the hydroxide ion (OH–).

Ethanol, or C2H6O, has two different types of bonding between its constituent atoms. The bonds between the hydrogen and carbon atoms are nonpolar covalent bonds. The hydrogen-oxygen and carbon-oxygen bonds are polar covalent bonds.

No; each CH3COOH molecule contains only one ionizable hydrogen atom. Only one of the four hydrogen atoms in the CH3COOH molecule can be donated because only those hydrogen atoms bonded to electronegative ele- ments by polar bonds are ionizable.

Other O-O Bonds Hydrogen peroxide, HOOH, has a very weak O-O bond and is photolyzed by light of 845 nm. Its bond energy is only about 142 kJ/mol. Why do we see such large difference in the strength of oxygen-oxygen bonds in these molecules.

Answer and Explanation: A water molecule can form four hydrogen bonds. Water is made up of two hydrogen atoms and an oxygen atom.

Ethers can form hydrogen bonds to water, since the oxygen atom is attracted to the partially-positive hydrogens in water molecules, making them more soluble in water than alkanes.

Polar aprotic solvents contain no hydrogen atoms connected directly to an electronegative atom and they are not capable of hydrogen bonding. These are acetone, dimethyl sulfoxide, DMF (N,N-dimethylformamide), acetonitrile, HMF (hydroxymethylfurfural), crown ethers and others.

Answer and Explanation: HH, which can also be written as H2, is not a hydrogen bond even though it involves two hydrogen atoms. H2 is a molecule in which two hydrogen atoms...
