A single bond such as -C-x2212-H- has one sigma bond whereas- a double -C-C- and triple -C-x2261-C- bond has one sigma bond with remaining being pi bonds-xA0-The given molecule has 10-xA0-x3C3- and 3-xA0-x3C0- bonds-Hence- option A is correct-

How many sigma and pi bonds are there in the given molecule?H−C≡C−CH2−CH=CH2There are 3 pi bonds and 10 sigma bondsThere are 2 pi bonds and 4 sigma bondsThere are 8 sigma bonds and 2 pi bondsThere are 12 sigma bonds and 2 pi bondsThere are 12 sigma bonds and 4 pi bonds

A single bond such as (C−H) has one sigma bond whereas, a double (C=C) and triple (C≡C) bond has one sigma bond with remaining being pi bonds. The given molecule has 10 σ and 3 π bonds.Hence, option A is correct.

A single bond such as $(C - H)$ has one sigma bond whereas, a double $(C = C)$ and triple $(C \equiv C)$ bond has one sigma bond with remaining being pi bonds.
The given molecule has $10 σ$ and $3 π$ bonds.

Hence, option $A$ is correct.
