# Methyl 2-cyanoacrylate is the active monomer in fast-acting adhesives (super glues). The complete Lewis electron-dot diagram for a molecule of methyl 2-cyanoacrylate is shown below.

Based on the diagram, what are the total number of \(\sigma\) bonds and \(\pi\) bonds in one molecule of methyl 2-cyanoacrylate?

Methyl 2-cyanoacrylate is the active monomer in fast-acting adhesives (super glues). The complete Lewis electron-dot diagram for a molecule of methyl 2-cyanoacrylate is shown below.

Based on the diagram, what are the total number of \(\sigma\) bonds and \(\pi\) bonds in one molecule of methyl 2-cyanoacrylate?

![A complete 2D Lewis electron-dot structure of methyl 2-cyanoacrylate. At the far left, carbon atom C1 is bonded to two hydrogen atoms via two single bonds (one angled up-left, one angled down-left). C1 is connected by a horizontal double bond to carbon atom C2. Carbon atom C2 is bonded upward via a single vertical bond to carbon atom C3; carbon atom C3 is triple-bonded upward to a nitrogen atom N, which has one lone pair of electrons directly above it. Carbon atom C2 is also bonded to the right via a single horizontal bond to carbon atom C4. Carbon atom C4 is double-bonded upward to an oxygen atom that has two lone pairs of electrons (one top, one right). Carbon atom C4 is single-bonded to the right to an oxygen atom that has two lone pairs of electrons (one top, one bottom). This second oxygen atom is single-bonded to the right to carbon atom C5. Carbon atom C5 is single-bonded to three hydrogen atoms (one top, one right, one bottom). No other atoms, bonds, lone pairs, or formal charges appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790596804-fevGGv.jpg)
