I look there in this question, they have given two species that is ethene and ethyne and ethyne, that is cx, superborne, ph.
00:17
And they have asked that each one having stronger bone.
00:22
The answer is ethyne, that is ph, superbore c .h, having stronger bone.
00:34
What is the reason? see as you know that alkyines are usually stronger having usually stronger bonds than alipine and alkyne so ethene belongs to alkyne group so that's why the eithi having stronger bonds the second question is the second question they have given four bonds that is receive bond three and co -bond and they have asked that which one having longer bond the answer is the ecb bond is longer.
01:11
Why because as you know that the carbon nitrogen oxygen story there belongs to first period as you know along the period atomic is decreasing.
01:21
So small and better they are going to form stronger the bonds in case stronger the bond the bond the length is shorter.
01:29
Here ac bond is weaker bond as compared to remaining so in this case the bond length is longed.
01:36
The third opportunity is they have asked her that which one is more polar bond? so the answer is tf bond is more polar.
01:46
Why because as you know that fluorine is most electronectrine limit in the period cable? that is why it makes the bond is more polar.
01:55
That is why the f bond is more polar because the fluorine is most electroneximate limit in the period table.
02:01
This is the answer.
02:03
The fourth question is, write the biggest or structure for most polar bond.
02:10
It is not possible to write only for c of bond.
02:13
So for that we are going to consider c.
02:16
S .m .r.
02:17
For that, we are going to write c .bisd structure.
02:20
See? in t .i .3 of molecules, how many various electrons are there? that one first we have to find out.
02:27
First, in t .h3 molecules, there are carbon, hydrogen and fluorine atom is present.
02:35
The valent electron of fluorine carbon is 4 plus the valent electron of hydrogen.
02:40
Is 1 but here there are 3 hydrogen atoms are there multiply with 3 plus and the valence electron of fluoride is 7 so it becomes 14 it means there are 12 valence electrons for making h .3 of molecules now i am going to draw leaving dot structures for this and carbon at the center which is surrounded by three hydrogen and one story and rate non -bound electrons are fluoride also this is the lewis dot structure of the h .83 of molecule.
03:14
In this molecule there are protein electrons present.
03:17
1, 2, 3, 4, 6, 7, 8, 9 10, 11 to 0 % percent poked.
03:23
These are the total electron which is presenting th3 of molecules...
