Hello everyone.
00:01
So before starting ahead, moving ahead with a question, i would like to explain you a little bit about the hook law because a hook law is a thing which is going to be helpful to solve this particular questions directly.
00:16
So we can say that a hook law is nothing but the wave number is directly proportioned to the force constant and the inversely proportion to the reduction or we can say reduce mass.
00:27
I can write it that according to the hook law, law, the equation which is a forming, the equation which is a forming like this way, frequency or we can say wave number is directly proportioned to the force constant 1 divided by 2 by c under root k divided by mu.
00:52
So where this one is what, this one is my wave number.
00:56
I would like to write it over here, wave number.
01:01
And k is what k is a bond strength bond strength and mu is what reduce mass reduce mass so according to that we have been provided over here the bunch of mcqs we need to find out which one is the correct options amongst them so moving ahead with the first part that is a hook law going to be dedicated that i are stretching frequency i are stretching frequency are dependent on whom.
01:43
So our answer would be are dependent on the bond strength, bond strength and the molar mass of an atom.
01:58
The answer is this molar masses of the atom.
02:05
Now, we are moving ahead with the second part.
02:09
From the above relation, we can proposed that the hook law, we can conclude that answer would be, okay, i would like to write it.
02:19
From the above relation proposed by whom by, we can conclude that what we can conclude, this will be the answer, that bond strength decreases, wave number of higher stretch with b decreases.
02:50
Wave number of ir stretch of i can write it this part as in wave number and ir stretch will be also decreases.
03:15
This is the answer.
03:17
Now moving ahead with the third part, i can write it over here.
03:22
Here the difference in the electromagnetic or so sorry, electronegativity.
03:29
Order would be the order i would like to represent over here oxygen greater than nitrogen greater than cl greater than h the electronegativity of h plus atom is lower so the bond strength of a ch is a weaker and we knowing if a bond strength is low stretch is low a stretching of the frequency is also low so what answer would be what c h i can write a c h bond would have the lowest i .r stretching frequency...
