Hello students, let's begin with this question.
00:02
Here the structure of this lactic acid is given and firstly we have to write down the molecular geometry shape of carbon atom 2.
00:18
So, here this carbon atom 2, this is bonded to, this is bonded to other three atoms and it will has and has no lone pairs.
00:39
So, its molecular geometry is the trigonal planar.
00:46
Now, the next part is, in the next part we have to write down the electron geometry of the oxygen atom 3, that is this one.
01:03
So, here the oxygen is, this is bonded, oxygen is bonded to other two atoms and has the two lone pairs.
01:19
So, this will have the bent geometry.
01:27
Now, in the next part, in the third part, here the approximate, approximate bond angle labeled b, labeled b is, so now here we have to, so in the given structure here, this is the bond angle a and this is the bond angle b.
02:04
So, here this bond angle b, this will have a trigonal planar geometry.
02:13
So, its bond angle is 120 degree.
02:17
Now, in the fourth part, the hybridization with oxygen atom 3.
02:30
Now, here if we see here, this third oxygen atom, this will bonded to two other atoms.
02:41
So, oxygen bonded to two other atoms and two lone pairs.
02:50
So, this will has the sp3 hybridization.
02:56
Now, in the next part, in the fifth part, the hybridization associated with the oxygen atom 4.
03:10
Now, in the structure, this oxygen atom 4, this will be double bonded to the carbon atom.
03:22
So, this will has the sp2 hybridization.
03:26
Now, in the sixth part, the number of pi bonds in the lactic acid...
