How many σ and π bonds are present ineach of the following molecules

1.	How many σ and π bonds are present ineach of the following molecules?(a) HC CCH-CHCH, (b) CH2-C-CHCH
Answer» a) A triple bond has 2 pi bonds and double bond has one pi bond and rest are sigma bonds. Thus total pi bonds =3 total sigma bonds = 9 b) A triple bond has 2 pi bonds and double bond has one pi bond and rest are sigma bonds. Thus total pi bonds =2 total sigma bonds = 9 First ka ans?

Answer»

a) A triple bond has 2 pi bonds and double bond has one pi bond and rest are sigma bonds.

Thus total pi bonds =3

total sigma bonds = 9

b) A triple bond has 2 pi bonds and double bond has one pi bond and rest are sigma bonds.

Thus total pi bonds =2

total sigma bonds = 9
