A Note on the Structure of Acetylene 321 



io 5 /(Mol. Wt), we obtain the value 10.06 for n. There are, 

 therefore, ten valences in the molecule of acetylene; accordingly 

 each carbon has four, each hydrogen one. 



Acetylene is, therefore, acetylene, as it is ordinarily written, 

 and not acetylidene.
