Identify the molecular formula and connectivity of cyanoacetylene (HC\_3N), which consists of a hydrogen atom bonded to a carbon chain of three carbons, ending with a nitrogen atom.
Recall that cyanoacetylene is known to be a linear molecule due to the presence of multiple bonds and sp hybridization in the carbon chain and nitrogen.
Determine the bonding pattern by considering typical bonding preferences: hydrogen forms one single bond, carbon can form up to four bonds, and nitrogen typically forms three bonds with a lone pair.
Assign a single bond between the hydrogen and the first carbon atom, as hydrogen can only form one bond.
Place a triple bond between the first and second carbon atoms, a single bond between the second and third carbon atoms, and a triple bond between the third carbon and the nitrogen atom to satisfy valence requirements and maintain linearity.
