Why is pentalene kinetically unstable ?
Options:
Answer:
B
Solution:
Pentalene has 8 π electrons around its planar periphery (4n, n = 2) and is anti-aromatic. The destabilised π system reacts rapidly, for example by dimerisation, so the compound is kinetically unstable and can only be kept at low temperature.
