This molecule is ammonia - NH3.
a hydrogen bond
Yes, nitrogen molecules are smaller than butane molecules. Nitrogen molecules consist of two nitrogen atoms, while butane molecules consist of four carbon and ten hydrogen atoms. Carbon atoms are slightly smaller than nitrogen atoms, but four of them are definitely larger than two nitrogen atoms, and of course, there are also the ten hydrogen atoms, and although hydrogen atoms are the smallest type of atom, if you have ten of them it does contribute to the size of the molecule. Further to this, the distance between bonds will be smaller in N2 as this is a triple bond because of 3 shared electrons each, whereas it is single bonds between the carbons, elongating the bonds between carbons
Hydrogen bonds are formed within molecules. In chemistry, they are the strongest of the 3 types of bonds (London Dispersion, Dipole-Dipole, and Hydrogen Bonding). Molecules that have hydrogen bonds have to have bonds between hydrogen and nitrogen or hydrogen and oxygen or hydrogen and fluorine (N-H, O-H, or F-H).
the bond between two water molecule is hydrogen bond.
Hydrogen
Intramolecular forces; Hydrogen bonds occur in ammonia between the nitrogen and the hydrogen, NH3.Intermolecular forces:Hydrogen bonding between molecules occurs between the electronegative nitrogen atom (N) of one molecule of ammonia and an electropositive hydrogen atom (H) bonded to a nitrogen of different molecule of ammonia.
a hydrogen bond
between the nitrogen bases of the two strands of DNA
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
Oxygen has a higher electronegativity than nitrogen does, so when sharing electrons with hydrogen, the sharing is more uneven in the case of oxygen than it is with nitrogen. Oxygen, in other words, will attract electrons more strongly than nitrogen does and therefore will wind up with a more negative charge (hydrogen, which supplies the extra electrons to the oxygen, has a correspondingly higher positive charge).
Polar covalent bond between nitrogen and hydrogen atoms Polar covalent bond between nitrogen and hydrogen atoms.
Amides have some hydrogen bonding, between the lone pair on the nitrogen and the hydrogen on the nitrogen in the next molecule. There will also be van der Waals forces and a little dipole-dipole attraction.
in pure water, no. Water is comprised of two hydrogen molecules and one oxygen molecule
Nitrogen is both an element and a molecule. In molecular form, Nitrogen forms a binary molecule N2 with a triple bond between the two Nitrogen atoms.
Nitrogen (and oxygen and hydrogen) in the form of a gas is usually found as a molecule of two atoms of Nitrogen. That is N2. The fairly weak bond can be broken chemically, by heat, etc, and then you would have N.
The question makes no sense. There's no such thing as a "nitrogen bond". If you mean "nitrogen atoms", then there are no hydrogen bonds between nitrogen atoms. If you mean "hydrogen bonds between a hydrogen and a nitrogen", then they break like any other hydrogen bond; they aren't really "bonds", just relatively strong electrostatic forces.
The two strands of a DNA molecule are held together by hydrogen bonds that occur between the nitrogen bases of both strands. The hydrogen bonds occur between the adenine and thymine nitrogen bases and between the cytosine and guanine nitrogen bases. Hydrogen boding occurs between Nitrogen or oxygen atoms (containing lone pairs of electrons in their outer orbital) and hydrogen atoms. They are weaker than covalent bonds but stronger than intermolecular forces.
