**Methyne** do not exist in nature because the **alkyne** family have the general formula** C** _{n }**H** _{2n-2 }where n is a natural number(which starts from 1). If we substitute 1 in place of n, then we get the formula CH_{0} which cannot exist. So, the first member of this series is ethyne.

Hence, the structure of methyne is not possible to find out.
