Hi, in this question we are having four parts and we are given with structure of esprin here.
00:07
In the first part of the question we are asked to calculate number of pi bonds.
00:11
Pi bonds means double bonds.
00:15
Let us calculate the number of pi bonds here.
00:19
We can start here 1, 2, 3, 4 and 5.
00:26
We can see we are having 5 pi bonds in the structure of esprin.
00:33
Now in second part of the question we are asked to calculate number of sigma bonds.
00:39
Sigma bonds means single bonds.
00:44
Here in each double bond there will be one single bond.
00:48
Therefore let us start counting from here as 1, 2, between oxygen and hydrogen there will be one sigma bond.
00:59
Therefore 3, 4, 5, 6, 7, 8, 9 and 10.
01:07
Between carbon and hydrogen there will be one sigma bond.
01:12
Therefore 11, 12, 13, 14, 15, 16, 17, 18 and there are 3 carbon hydrogen bonds here...
