Hello, here it is given that hello alkenes undergo substitution reactions where the halide ions, that is, fluorine, chlorine, bromine and iodine are living groups.
00:14
Here we need to find out among all those statements which one is the correct one, where the statement a is given us rf, that is, fluoralkane are more reactive than the iodokin's.
00:28
Because the electronegativity of fluorine is greater than i, that is iodine, or rf more reactive than ri, as size of fluorine is smaller than the iodine, or the r i.
00:43
That is, iodoalkane, is more reactive than the fluoralkane, because the electronegativity of iodine is greater than the fluorine.
00:53
Or in the last statement is given us, the ri more reactive.
00:59
Than r f because the carbon iodine bonds is weaker than the carbon fluorine bond.
01:06
Here we should know about the bond energy.
01:11
What is this bond energy? the bond energy is the energy required to break a bond or energy released upon making a mole of that bond.
02:13
Here let's talk about the bond energy of carbon and halogens...
