Hey guys,
This is a question from the May/June 2002 Paper 2. In a chlorofluorocarbon, CHF2CHClF, the question asked which covalent bond is the weakest and the answer was the C-Cl bond. Does anyone know why the C-H bond is stronger than the C-Cl bond? And in that particular chlorofluorocarbon, CHF2CHClF, is the chemical inertness of this compound due to the very strong C-F bond?
Thank you in advance.
Everyone Good Luck with you exams.
Don't worry holidays is coming soon! ;D ;D

It's cause of the size and electronegativity. I will look for something to explain it.

Ok thanks nid. So is the chemical inertness of the chlorofluorocarbon due to the strong C-F bond?

Ok thanks nid. So is the chemical inertness of the chlorofluorocarbon due to the strong C-F bond?
yup....

Hi please reputate me if u find this usefull i will be gratefull :) :D ;D
Carbon and Chlorine both are more on the electronegative side so the bond is not as strong as C-H..bond as H is kind of electropositive..so I wud say the C-Cl bond has a lesser difference in elecronegativity and truly depend on weak Vanderwaal forces
-
well, the electronegativity of C and H no big difference compared to C and Cl.Cl is more elctronegativity and has more electron clouds at Cl causing the unequal distribution of electrons,and having this distortion making it less stable to heat and so C-Cl bond is the weakest.C-H bonds has less distortion due to almost symmetrical electron cloud.yes, chemical inertness due to C-F bond because the bond length is short and more overlapping of orbitals and need higer bond energy to break it. the higher the bond energy,the more difficult it undergoes reaction. raunaqbhatia theory is absolutely wrong, where u get that from?

Ok thanks a lot light, i understand it now ;D.

sorry dude but u wrong
