1. The problem statement, all variables and given/known data
Assuming the five basis atomic orbitals are normalised use the Huckel approximations to normalise the wavefunction for the cyclopentadienyl radical
Wavefunction = $$\phi_{1}+\phi_{2}+\phi_{3}+\phi_{4}+\phi_{5}$$.

2. Relevant equations

I know that $$\phi_{i}\phi_{j}$$ = 1 if i=j and 0 otherwise and I know that to normalise a wavefunction you square it and times by a constant.

In the end I got N=1/5

You're close, but you have things in wrong order.

First, you multiply the wavefunction by a constant.

Then you square it.

Following my suggestion will change that answer.
