The number of \( \pi \) bonds present in tetra cyano ethylene are 6

Tetra cyanoethylene, also known as tetracyanoethylene (TCNE), is an organic compound known for its unique chemical structure. It features four cyano groups (-C≡N) attached to a central ethylene (C=C) unit. In TCNE, each cyano group contributes a triple bond, which includes one \( \pi \) bond. Therefore, with four cyano groups, you have 4 \( \pi \) bonds from the cyano groups and 1 \( \pi \) bond from the double bond in the ethylene unit, resulting in a total of 5 \( \pi \) bonds. To avoid misunderstandings, it's crucial to recognize that while \( \pi \) bonds play a vital role in stabilizing structures and determining reactivity, they are also more reactive than \( \sigma \) bonds. Make sure to count all types of bonding correctly and consider their implications in reactions!
