Its no unpaired electrons because theres 2 unpaired electrons on N? If there was 1 it would be paramagnetic then? And to find Bond Order Bond order = 1/2 (Nb - Na) 1/2 (6 - 2) = 2 so its stable? Or am I wrong? Says Nb = bonding orbitals and Na = antibonding orbitals

This is ok but you omitted the double bond in CH2=CHCH2CH3. The double bond needs to be there (even though it's a condensed formula). When it's omitted the observer doesn't know if it is a double bond or if you just forget and left out the two H atoms.

Finance
A three-year bond has 8.0% coupon rate and face value of $1000. If the yield to maturity on the bond is 10%, calculate the price of the bond assuming that the bond makes semi-annual coupon interest payments.
