Which one of the following statements is incorrect with regard to ortho and para dihydrogen? (Kerala CEE 2009)

Para and ortho hydrogens are the allotropes of the hydrogen molecule and they differ in spins of protons. Hence, they are nuclear spin isomers but the ortho isomer has one nuclear spin whereas the para isomer has zero nuclear spin. Nuclear spin of ortho hydrogen = 1 1 1 2 2 (spin direction is same) Nuclear spin of para hydrogen = 1 1 1 1 0 2 2 2 2 or (spin direction is opposite)
