Which one of the following statements is incorrect with regard to orth

1.	Which one of the following statements is incorrect with regard to ortho and para dihydrogen ? (a) They are nuclear spin isomers (b) Ortho isomer has zero nuclear spin whereas the para isomer has one nuclear spin (c) The para isomer is favoured at low temperatures (d) The thermal conductivity of the para isomer is 50% greater than that of the ortho isomer.
Answer» (b) Ortho isomer has zero nuclear spin whereas the para isomer has one nuclear spin Correct statement: Ortho isomer – one nuclear spin Para isomer – zero nuclear spin
