Homework Statement
Consider a polyene consisting of N double bonds and assume the length of the box in which the π electrons are confined is Na, where a is a suitable lenght.
What would the length for hexatriene be? You will need to choose a value for a, and should justify your choice.
Hexatriene has 3 double bonds and 2 single bonds.
The Attempt at a Solution
The only thing I can think of us: doing avarage of length of c-c and c=c bonds, multiplying it by the number of double bonds and then by 2?
Lenght= N*2*BL BL= bond length
though you don't really have 2 time the number of double bonds.. that's what is messing me up.
hence a=2BL ?
