Hello everyone!
I have met such a curious thing: When chemists tried to synthesize CaCl by reducing CaCl2 with H2 they got CaClH instead, but the structure of a compound was determined using X-ray structure analysis which is not suitable for determining the position of light elemnts like hydrogen, thus the presence of hydrogen was missed and CaClH was thought to be a CaCl for a long time. Can anybody explain, why this X-ray technique cannot be applied to light atoms? Thank you.
