Which gas, acetylene (#C_2H_2#), a gas used in welding, or ethane (#C_2H_6#) has a stronger carbon to carbon bond energy and bond length? Explain why.
The triply bonded acetylene molecule............
The modern chemical bond is conceived to be a region of high electron density between 2 positively charged atomic nuclei, such that internuclear is repulsion is negated, and a net attractive force results. The idea can be extended to multiple bonding, where electron density is concentrated in planes NORMAL to the
So let's look at the bond dissociation energies. As chemists, as physical scientists, we must examine the data:

And representative values for
Are these data consistent with the argument just proposed?
