Answer 1

1, 3 pentadiene has similar pi molecular orbital decryption that of 1, 3 - octadiene. The pi molecular orbital description depending the similarity in resonating structure 1, 4-pentadiene This compound do not have conjugation and its pi molecular orbital distribution is as ethane = ethane 1, 3, 5 - heptadiene It has three pi molecular orbitals in conjugation which is similar to that of 1, 3, 5-hexadiene they shows similar resonating structure 1, 3, 5, 8 - nonattendance one pi-orbitals not in conjugation similar to that of ethane. 3 pi orbital in conjugation similar to that of 1, 3, 5 - hexameter
