An orbital view of the bonding in ethyne
Ethyne is built from hydrogen atoms (1s1) and carbon atoms (1s22s22px12py1). The carbon atom does not have enough unpaired electrons to form four bonds (1 to the hydrogen and three to the other carbon), so it needs to promote one of the 2s2 pair into the empty 2pz orbital.
Can Ethyne form hydrogen bonds?
Ethyne is more commonly known under the trivial name acetylene. It is the simplest of the alkynes, consisting of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom.
What type of bond is Ethyne?
Ethyne (C 2 H 2 ) is a linear molecule with a triple bond between the two carbon atoms (see Figure 4). The hybridization is therefore sp . Figure 4.
