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 does a negative decimal plus a negative decimal equal?
A negative decimal plus a negative decimal equals a more negative decimal
Is negative 1 less than negative 2?
no it is more
Fluorine is more electronegative than oxygen?
Yes it is more electro negative. F has the highest electro negativity
What is the electronegativity for sulfur?
Oxygen is more electro negative. It seconds only to fluorine
What is more reatice fluorine or chlorine?
Fluorine is more reactive than chlorine.
Which of these bonds are most polar H-Cl H-Br H-F?
No, H-F is more polar because fluorine, F, is more electro-negative than chlorine, Cl.
Would fluorine's chemical properties more closely resemble those of oxygen or those of chlorine?
Fluorine is more chemically similar to chlorine than it is to oxygen. Fluorine and chlorine both have 7 valance electrons, whereas oxygen has 6.
Which one has more electronegative chlorine or iodine?
Chlorine is more electro negative.Iodine has the lowest among halogens
Which is the more electronegative atom in bond B-F?
Fluorine is more electronegative. It has the highest electro negativity.
Is fluorine more reactive than chlorine?
yes
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
Why chlorine is highly reactive than other halogens?
It isn't. Fluorine is more reactive. However, Chlorine is more reactive than Bromine, Iodine and Astatine. It is all to do with molecular size. Fluorine wants to get to a stable 10 electrons to be like Neon more than Chlorine wants to get to get 18 lectrons to be like Argon. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and thus more strongly attracted.
What elements are more similar to chlorine?
Fluorine , Bromine , Iodine are similar to chlorine. They are non-metals placed in group-17.
