Passage / Comprehension

Based on the nuclear spin, hydrogen shows two types of isomers(i) ortho hydrogen (ii) para hydrogen ortho hydrogen, molecular form of hydrogen has same spin of nucleus, where as in para hydrogen, the molecular form of hydrogen has opposite spin of nucleus.

Find the correct order of internal energy -

Options:

Answer:

Solution:

Hydrogen molecules exist as two nuclear spin isomers: ortho-hydrogen and para-hydrogen.

In ortho-hydrogen, the two nuclei have the same spin direction, while in para-hydrogen they have opposite spin direction.

Ortho-hydrogen has higher rotational energy due to its higher energy state.

Therefore, the order of internal energy is:

$O r t h o h y d ro g e n > P a r ah y d ro g e n$
