How many sigma and pi bonds are present in the following (a) But-1 en

1.	How many sigma and pi bonds are present in the following (a) But-1 ene-3-yne (b) Buta-1, 3-diene ( c) CH_(2) = CH- C -= N (d) Propan-1, 2, 3 diene (e ) 1-butiene and 2-butane
Answer» Solution :(a) `CH_(2)= CH - CH -= CH` (Seven `sigma` and three `pi`) (B) `CH_(2)= CH- CH= CH_(2)` (Nine `sigma` and TWO `pi`) (C ) SIX `sigma` and three `pi` (d) `CH_(2)= C= C= CH_(2)` (seven `sigma` and three `pi`) (e ) `HC -= C- CH_(2)- CH_(3)` (Nine `sigma` and two `pi`)
