What causes polarity in water molecule?
When a highly electronegative atom is attached to a less electronegative atom, then the former one attracts the shared pair of electrons towards itself. Such a molecule is polar molecule. Polarity of molecule means the product of charge on molecule and the distance between the atoms.
The final electron acceptor of aerobic respiration is?
Oxygen, because it is highly electronegative.
Is DNA a polar or nonpolar molecule?
DNA is a polar molecule because it has a negatively (-) charged phosphate group attached to the 5' end of the molecule and a negatively charge hydroxl group (OH) attached to the 3' prime end of the molecule.Thus, it is a POLAR molecule which allows it to interact in an aqueous environment.
What is a series of highly folded membranes suspended in the cytoplasm with nothing attached to its outside?
mitochondria
Which elements are responsible for the greater part of plant wet weight?
water/ H2O or Hydrogen and oxygen, although carbon is also highly placed
Is c5h10 hydrogen bond?
No. In order for hydrogen bonds to form, hydrogen must be bonded to a highly electronegative element such as oxygen, nitrogen, or fluorine. In this molecule it is only bonded to carbon, which is not electronegative enough.
What is the bond between hydrogen atoms on one molecule and a highly electronegative atom on another molecule but not a full covalent bond?
time to get a life bro
What explain is negative charge on the oxygen atom within the water molecule?
Oxygen atoms are highly electronegative and pull electrons away from the electropositive hydrogen atom.
How many hydrogen bonds does H2 has?
Hydrogen molecule doesn't have any hydrogen bonds. It only has one bond between the hydrogen atoms and that too is a covalent bond. A Hydrogen bond is a weak interaction between a hydrogen atom and a highly electronegative atom such as oxygen, Fluorine etc.It is not actual bonding.
Is XeF2O polar?
This molecule will be polar because it has a t-shape arrangement, and fluorine is a highly electronegative element.
When is hydrogen bonding most likely to occur?
It is a common bond between hydrogen and nitrogen, fluorine, oxygen because these elements are highly electronegative.
Explain why water contains strong hydrogen bonds and h2s does not?
The hydrogen bond involves hydrogen in a covalent bond with a highly electronegative element, like oxygen in water. Pure hydrogen H2 involves 2 atoms with exactly the same electronegativity. In water the large difference in electronegativity means that the bond is polar covalent. In addition to that, the hydrogen is not quite, but nearly a point nucleus because there are no other electrons in hydrogen than those shared. This causes a very strong attraction --- not a real bond -- between the hydrogen and the highly negative oxygen in an adjacent molecule. This is the real hydrogen bond, the attraction of the hydrogen for an element in another molecule. Real bonds are within one molecule.
The water molecule has a dipole with the negative portion?
Water (H20) is a polar covalent molecule with two highly electronegative oxygen atoms. The electronegative oxygen atoms create a dipole moment, and are also cause H20s bent shape.
Why hydrogen bond in water is stronger than in HF and NH3?
In HF molecule hydrogen bonding is the strongest. The reason is that the partial positively charged hydrogen atom is entrapped between the two highly electronegative fluorine atoms.
What is the comparison between a hydrogen and covalent bond?
Covalent bonds are generally irreversible once formed. They occur when two atoms share a pair of electrons between them. Hydrogen bonds aren't really 'bonds' but are more interactions. Of the two atoms involved in hydrogen bonding, one is highly electronegative (such as oxygen or nitrogen) which is called the Hydrogen Bond Acceptor, and the other is a hydrogen atom attached to an electronegative atom (-OH, -NH2, -SH). This hydrogen is the Hydrogen Bond Donor. This hydrogen is very positive due to being bonded to a electronegative atom. The large different in partial charges between the hydrogen bond donor and the hydrogen bond acceptor leads to them interaction by weak electrostatic attraction.
Why there is hydrogen bonding in water but not in hydro cloric acid although both have hydrogen?
FONFlorineOxygenNitrogenThe hydrogen must be bonded to one of these highly electronegative atoms to participate in hydrogen bonding.HClChlorine is not of this group shown above. Do you know why?
What is the difference between hydrogen bounding and covalent bonding?
Covalent bonding is a chemical bond formed when two atoms share electrons. Hydrogen bonding is a form of strong intermolecular attraction between molecules in which hydrogen is bonded to a highly electronegative element such as nitrogen, oxygen, or flourine. In these molecules the hydrogen atom(s) gain a partial positive charge and the electronegative atom gains a partial negative charge. The positive end of one molecule attracts the negative end of another and vice versa.
