Hello, in this question the structure of ll sinai is given, we have to find out the number of sigma bonds, five bones and valance electrons first of all we have to find sigma bonds.
00:11
What are sigma bonds? sigma bonds are formed by the sharing of two electrons so it will be single bonds.
00:22
So it has come to single bonds here that is one, two, three, four, five, six, seven, eight.
00:30
So the number of sigma bonds here will be equal to eight.
00:33
Next we have to find out the five bonds.
00:39
Five bones are usually unsaturated bonds that means they will be double bones.
00:48
That is formed by the pairing of four electrons.
00:51
So just count here.
00:52
On counting it is 1, 2...
