Question

How many sigma pi bonds are present in nitrogen molecule of cumulene?

Answer 1

Answer:

This is a molecule of cumulene, C4H4 . Single bonds are one σ -bond, while double bonds are one σ and one π -bond.

Answer 2

There are two pi and sigma bonds present in nitrogen molecules and 7 sigma and 3 pi bonds are present in cumulene.

• The nitrogen molecule contains an N-N triple bond. In a triple bond two 'pi' and one sigma bond is present so, the nitrogen molecule has two "pi" and one sigma bond.
• Again, the structure of cumulene is as follows-
• $H_2C=C=C=CH_2$
• It contains seven sigma bonds four between C and H and three between Carbon atoms. Again it contains three pi bonds.
