Which of the following acids would have the highest electronegativity?
A. PH3
B. HCl *********
C. H2SO4
D. H2S
this question say it does.... thats why Im confused
Its HCI.
Hot steamy and bubbly goose poop my guy
put it on some icecream like hot fughe and mdksjnfkncd its so good
i mean goose poop
i CANT SAY P00P
So Gage are you saying b. Is the answer?
To determine which acid among PH3, HCl, H2SO4, and H2S has the highest electronegativity, we need to understand what electronegativity is and how to compare it for different atoms or molecules.
Electronegativity is a measure of an atom's tendency to attract a shared pair of electrons towards itself when it bonds with other atoms. It helps us understand the polarity of a bond between two atoms.
There are several ways to determine the relative electronegativity of different elements. One commonly used scale is the Pauling electronegativity scale. According to this scale, fluorine (F) has the highest electronegativity value of 4.0, while other elements are compared relative to it.
Now, let's examine each of the given acids and compare their electronegativity:
a) PH3 (Phosphine): Phosphorus (P) has an electronegativity of 2.19, according to the Pauling scale.
b) HCl (Hydrochloric acid): Hydrogen (H) has an electronegativity of 2.20, and Chlorine (Cl) has an electronegativity of 3.16. Since Chlorine has a higher electronegativity than Phosphorus, HCl will have a higher electronegativity than PH3.
c) H2SO4 (Sulfuric acid): Hydrogen has an electronegativity of 2.20, and Sulfur (S) has an electronegativity of 2.58. Again, Chlorine has a higher electronegativity than Sulfur, so HCl has a higher electronegativity than H2SO4.
d) H2S (Hydrogen sulfide): Hydrogen has an electronegativity of 2.20, and Sulfur has an electronegativity of 2.58. Since Sulfur has a higher electronegativity than Phosphorus, H2S will have a higher electronegativity than PH3.
Based on these comparisons, we can conclude that among the given acids, HCl has the highest electronegativity.
