CBr4

CBr4 or tetrabromometha has the highest of the three with a boiling point of 190 degrees Celsius. This is because Bromine has the highest boiling point when compared to Flourine and Clhorine.

Boiling Point Of Cf4
2016-10-30 04:48:38 · answer #2 · answered by detkowski 4 · 0⤊ 1⤋
CF4 since it has the highest difference in electronegativity; meaning, F is the most electronegative among Cl, and Br, since it attracts electrons better than both of them. Carbon, on the other hand, is not so electronegative, meaning, its ability to attract electrons to its nucleus is much lower than that of F. Therefore, the toughest bond to break would be the one in which there is the highest difference in electronegativity- because, the F attracts the carbon's electrons the most, more than Cl and Br, and it would therefore be harder to separate them, translating in having the highest boiling point.
I hope this helped. Good Luck.

If it has hydrogen bonding capability, that will give it a high boiling point. Any alcohol has hydrogen bonding! So, the hexyl alcohol will have the highest boiling point.

ANSWER is CF4 becauuse f is the most electronegative. So it is more polar .that us it will try to make strong bond with cabon as well as surrounding molecules,so for boiling more heat will be needed

CF4. If you use an electronegativity chart and subtract each element from the value of carbons....you would see that F has the highest difference in electronegativity. So it is more polar. Which means it takes more energy to break each molecule away from the other.

CF4 because F is the most electronegative element. Therefore it will take more energy to break the C-F bond than it will to break a C-Br or C-Cl bond.
