The H-F bond is more polar than the H-I bond because F (fluorine) is more electronegative than I (iodine). It thus attracts the shared electrons more than does the I, making it a more polar bond.
The H-F bond is expected to be more polar than the H-I bond because F has the highest electronegativity.
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.
C-H bond is stronger
polysaccharides have more chemical bond
Unsaturated bond
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.
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.
Its more a matter of whether the bond has a smaller angle than bonds in other very similar compounds. A smaller angle than expected is said to cause strain- i.e. it breaks more easily. Examples from organic chemistry include cyclo alkanes with bond angles less than tetrahedral.
Hydrogen fluoride has a Polar-covalent bond although, while the difference in electronegativity is more than 1.7 ( we expected to be Ionic ).
In the sentence 'She visited us more often than we expected' yes, expected is a right form in this sentence.
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.
James Bond is more famous than Rhianna.

An atom can make more than one bond if it has more than one unpaired valence electron.
An atom can make more than one bond if it has more than one unpaired valence electron.
A share is more of a risk than a bond.
As-F bonds should be more polar, because fluorine is the most electronegative of all elements.
