The correct answer is statement 3, the difference in electronegativity between carbon and oxygen is greater than that between fluorine and oxygen. The most polar bond is the one with the highest difference in electronegativity values between two atoms. In this case, the C-O bond.

Answer: (3) The difference in electronegativity between carbon and oxygen is greater than that between fluorine and oxygen.

Explanation: Polarity of a molecule is due to the difference in electronegativity of the atoms. More is the electronegativity difference, more is the polarity.

Electronegativity of carbon = 2.5

Electronegativity of oxygen = 3.5

Electronegativity of fluorine = 4.0

Thus the difference in electronegativity of carbon and oxygen is=(3.5-2.5)= 1.0

Thus the difference in electronegativity of fluorine and oxygen is=(4.0-3.5)= 0.5.

Thus C-O bond is more polar than F-O bond.

Answer:Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some could tolerate. After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings. Unwilling to challenge the data openly, they erased the report from public view without a word to the authors. When the authors inquired, they received this letter:

hichkok12 [17]

Answer:
Arachidonic Acid and PGE₁ are both carboxylic acids with Twenty Carbon atoms. The differences are that Arachidonic acid contains Four cis Double Bonds and no other functional groups, whereas PGE₁ has One Trans Double Bond, Two Hydroxyl and One Ketone Functional Groups.. In addition, a part of the PGE₁ chain forms a Five Membered Ring.

Structures of Both Arachidonic Acid and PGE₁ are shown Below,

What is the condensing point of water

lorasvet [3.4K]

The condensation point of water is the same as the boiling point of water. This occurs at 212 degrees Fahrenheit or 100 degrees Celcius. As you increase water up to end beyond 100 degrees celcius, the water will boil
