Why water is liquid at room temperature give 2 reasons?
The inter molecular hydrogen bonding between oxygen and hydrogen of different water molecules results in the liquid state of water
What type of bonding is found in methanol CH4Ol?
Methanol, CH3OH (CH4O) is a covalent molecular compound. It is liquid under normal conditions and there is hydrogen bonding between molecules
What type of bond does ammonia have?
polar covalent
What is between the molecules of liquid water?
Water molecules are linked by hydrogen bonds.
Most substances that have molecules with approximately the same weight as water molecules are gases at room temperature. Water is a liquid at room temperature. Water is a liquid at room temperature be?
...because water molecules have strong intermolecular forces (hydrogen bonding) holding the moelcules together in the liquid state. Most other substances with similar molar mass do not exhibit hydrogen bonding, and thus they exist as gases.
What is the most important role of hydrogen bonding between water molecules?
The molecules of water are held together by hydrogen bonding between molecules.These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive and the oxygen in the water molecule is slightly negative. Hydrogen gets attracted to the neighbouring slightly negative oxygen atoms.This is great for life on Earth because small molecules the size of water tend to be gases but water is a liquid. It is a liquid due to the hydrogen bonding between molecules.
Water molecules can bond to other water molecules by hydrogen bonding?
Not only can they, but in the liquid state they do so continuously. Hydrogen bonding between water molecules gives it many of its unique properties, such as being a liquid at standard conditions, which is essential for life; high heat capacity and heat of vaporization; and the fact that solid water is less dense than liquid water.

What is promarily responsible for holding water molecules together in the liquid state?
hydrogen bonding.
What is the strongest intermolecular force in a liquid containing molecules with H O bonds?
Hydrogen bonding.
What type of bond does ammonia have?
polar covalent
Why ethyl alcohol is a liquid while ethyl chloride is a gas?
Ethyl alcohol is a liquid because strong hydrogen bonding in it brings the molecules closer together while methyl chloride does not form hydrogen bonding,weaker forces exist between molecules of methyl and chloride due to which they lie at distance from each other till gas form.
Why boiling point of H2O is greater than H2S?
Although both molecules are polar and have similar masses, the O-H bond in water is highly polar, producing a dipole movement in the overall molecule towards O. The S-H is also polar and produces a dipole movement towards S, but it is not as strong a separation of charge as that produced by O-H. This results in H20 molecules being more strongly attracted to each other by Hydrogen bonding, than H2S molecules which are attracted to each other due to only dipole-dipole attraction. Stronger attraction between molecules means it takes more energy to separate them into the gas phase, making it have a higher boiling point.
Are there hydrogen bonds between molecules in steam?
Water is a polar substance. In liquid water, this gives rise to hydrogen bonds between molecules, making it structurally more compact. However when water is heated up to steam, those hydrogen bonds break up and the molecules cannot be maintained globally as aggregates. The forces in play in steam are of collisional type and the polarity of the molecules does result in short-range attractive forces yielding negative second virial coefficients but in no way the molecules arrange themselves to conform to a hydrogen-bonded structure. The probability of simultaneous collision between several molecules though rare in steam may become important at high pressures below the critical point, but should not be confused with the structuration between neighbouring molecules in liquid water where hydrogen bonding takes place due to the closeness between water molecules. What is sure is that there is no hydrogen bonds above the critical point of steam. In steam hydrogen bonding is just not taking place for the molecules are too distant from each other. Collisional binary encounter does not generate hydrogen bonding!!!
