What is the molecular shape around the central atom in CF2Cl2?
The molecule that you describe, which would more accurately be written as CCl2F2 is the same shape as a methane molecule; the carbon is in the center, and it is surrounded by a symmetrical arrangement of two chlorine and two fluorine atoms, which are at the points of a tetrahedron.
Why standard reduction potential of fluorine is greater than cl2?
Fluorine and chlorine both need to gain electrons in order to achieve a stable electron configuration of 8 electrons in their outer shell, but fluorine is the smaller atom. As atoms get larger, their ability to attract electrons is reduced and they become more metallic in nature and less nonmetallic, because the outer shells of the electrons are farther from the positively charged nucleus, and even though the nucleus of larger atoms also has a larger positive charge, the increase in charge has less effect than the increase in distance, because charge is a direct proportionality and distance is an inversely squared proportionality. Distance matters more. So fluorine has the greater attraction for electrons, or as you put it, it has the greater reduction potential.
What is the more negative -.001 or-. 01?
They are equally negative. -0.001 is the greater number.
What numbers get more negative on a number line?
On a number line, numbers become more negative as they move leftward. For instance, -1 is less negative than -5, meaning -5 is more negative. Therefore, any number with a larger absolute value but a negative sign, such as -10 compared to -3, is more negative. In summary, the further left you go on the number line, the more negative the numbers become.
What does a negative decimal plus a negative decimal equal?
A negative decimal plus a negative decimal equals a more negative decimal
Which of these bonds are most polar H-Cl H-Br H-F?
The H-F bond is the most polar because fluorine is the most electronegative element among chlorine, bromine, and fluorine. The greater the electronegativity difference between the elements in a bond, the more polar the bond.
Fluorine is more electronegative than oxygen?
That is correct. Fluorine is the most electronegative element on the periodic table, meaning it has a strong ability to attract electrons in a chemical bond. Oxygen is also very electronegative but not as much as fluorine.
What is more reatice fluorine or chlorine?
Fluorine is more reactive than chlorine. This is because fluorine has a higher electronegativity and a smaller atomic size, making it more eager to gain an electron and form bonds with other elements.
Would fluorine's chemical properties more closely resemble those of oxygen or those of chlorine?
Fluorine's chemical properties more closely resemble those of chlorine, as both are halogens. They can both readily gain an electron to form a negative ion and have similar reactivity and electronegativity. Oxygen, on the other hand, tends to form covalent bonds rather than ionic bonds like fluorine and chlorine.
Is fluorine more reactive than chlorine?
Yes, fluorine is more reactive than chlorine. This is because fluorine has a higher electronegativity and smaller atomic size, making it more able to attract and gain electrons in chemical reactions compared to chlorine.
Which has highest electron gain enthalpy between chlorine and fluorine and why?
Even though Fluorine has the highest electronegativity among all the elements and it should have the highest electron gain enthalpy among all the halogens but this is an exception and chlorine has higher electron gain enthalpy than Fluorine. The reason for this is that the size of Fluorine atom is very small and hence there is very high inter-electronic repulsion among the electrons of fluorine. This makes incoming of another electron not very favourable. Even though fluorine has large negative electron gain enthalpy but for chlorine its even more negative.
Is iodine a positive or negative charge?
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
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.
Why is fluorine more electronegative than both lithium and chlorine?
Fluorine is more electronegative than lithium and chlorine because it has a greater nuclear charge and a smaller atomic size. These factors result in a stronger attraction for electrons in the fluorine atom, making it more electronegative compared to lithium and chlorine.
Is fluorine similar properties to chlorine?
Yes, fluorine and chlorine are both halogens and share similar properties such as being highly reactive and having similar chemical behaviors. However, fluorine is more reactive and has a smaller atomic size compared to chlorine.
What kind of bond is there between sulphur electro negative value 2.5 and chlorine electro negative value 3.0?
The bond between sulfur (electronegativity 2.5) and chlorine (electronegativity 3.0) would be classified as a polar covalent bond. This is because of the difference in electronegativity between the two atoms, causing a partial transfer of electron density towards the more electronegative chlorine atom.
Why is fluorin more reactive then chlorine?
Fluorine is more reactive than chlorine because fluorine has a smaller atomic size, leading to a higher effective nuclear charge that attracts electrons more strongly. This makes it easier for fluorine to gain electrons and form stable compounds by filling its valence shell. Additionally, the higher electronegativity of fluorine makes it more likely to undergo chemical reactions compared to chlorine.
