How are hydrogen atoms arranged in ethene? in -different planes, separated by angles of 180° in -the same plane, separated by angles of 120° in -the same plane, separated by angles of 1800 in -different planes, separated by angles of 1200​

Explanation:

How best to demonstrate the equivalence of hydrogens in  

H 2 C = C H 2 ?

1 H NM R spectroscopy would be the best way to show this. The 4 hydrogens give the one signal.

Explanation:

in the same plane sep by angles by 120o
