the element carbon has multiple boding patterns . which bonding cannot be formed by carbon
a) c-c
b)c-c-c
c) c=c=c
d)c=c=c (three lines for this one)

Respuesta :

The incorrect bonding would be D. If there are 3 lines in between each carbon then this breaks the octet rule. The carbon in the middle will have more bonds than it is allowed.
