Why is 5-Fluorouracil more stable than uracil?
5-fluorouracil is more stable than uracil as it has a C-F bond while uracil has a C-H bond. The C-F bond is more stable as F is very electronegative so the bond is stronger.
Why c-c bond is more stronger than C-H bonds?
C-H bond is stronger
Why can more complex suger polysaccharide store more energy than a monosaccharide?
polysaccharides have more chemical bond
Why bond energy of H-F is greater than H-Br?
The bond energy of H-F is greater than H-Br because fluorine is more electronegative than bromine, resulting in a stronger bond between hydrogen and fluorine due to increased attraction. This stronger bond requires more energy to break, leading to a higher bond energy in H-F compared to H-Br.
What is a bond in which one atom is much more electronegative than the other?
A polar covalent bond because: When two atoms with different electronegativities form a covalent bond, the shared electrons are more likely to be closer to the atom of higher electronegativity rather than the atom of lower electronegativity.
Is an N F bond expected to be more polar than an 0 F bond?
The electronegativity of N O and F are 3.0 3.5 and 4 respectively according to the Pauling's scale. The electronegativity difference between N and F is greater than the difference between O and F. So, the prior bond is expected to be more polar.
What bond will be expected to be more polar As Cl or As F?
The As-F bond will be more polar than the As-Cl bond. This is because fluorine is more electronegative than chlorine, leading to a greater difference in electronegativity between the atoms and a more polar bond.
She visited us more often than we expected Is expected a right form in this sentence?
In the sentence 'She visited us more often than we expected' yes, expected is a right form in this sentence.
What type of bond forms between sulfur and chlorine is it polor covalent or non polar covalent?
A polar covalent bond forms between sulfur and chlorine. Sulfur is less electronegative than chlorine, causing an uneven sharing of electrons and creating partial charges on the atoms.
What does OR on a us savings bond mean?
Ok when you buy a saving bond you are giving money to the US and over time you are expected to get more money out of the savings bond than you bought it for. Like you bought a $10 saving bond 20 years ago. When you go to cash it in you expect to get $35. But im not sure about the rates.
Who is more famous James Bond or Rihanna?
James Bond is more famous than Rhianna.
Is James Bond more famous than Mario or less?
mario is more famous
Why it possible for an atom to make more than one bond?
An atom can make more than one bond if it has more than one unpaired valence electron.
Compare the relative polarities of the OH-bond and NH bond?
The OH bond is more polar than the NH bond because oxygen is more electronegative than nitrogen, leading to a greater difference in electronegativity between oxygen and hydrogen. This means the OH bond has a greater separation of charge and greater polarity than the NH bond.
More than is usual or expected?
Neither
Does a stock or bond represent more risk to the company?
A share is more of a risk than a bond.
Which bond is more polar a phosphorus fcholrine bond or a phosphorus fluorine bond?
A phosphorus-fluorine bond is more polar than a phosphorus-chlorine bond. Fluorine is more electronegative than chlorine, so it withdraws electrons more strongly in a covalent bond, resulting in a greater difference in electronegativity between phosphorus and fluorine compared to phosphorus and chlorine.
