Question

the image shows tubes of glue and a lewis structure for methyl cyanoacrylate, the chemical component of superglue. a lewis structure for methyl cyanoacrylate is shown in the image. this lewis structure has at least one carbon atom with the incorrect number of valencies. how many carbons have the incorrect valence (the incorrect normal number of bonds)? one carbon atom two carbon atoms three carbon atoms four carbon atoms

Explanation:

Step1: Recall carbon's valence

Carbon has a valence of 4, meaning it typically forms 4 bonds.

Step2: Analyze the Lewis - structure

Examine each carbon atom in the methyl cyanoacrylate Lewis - structure for the number of bonds.

Step3: Count carbon atoms with incorrect valences

Upon inspection, we find that one carbon atom has an incorrect number of bonds.

Answer:

One carbon atom
