Question

Super glue or crazy glue is:
A: Polymethyl methacrylate
B: Poly Ethyl acrylate
C: Poly Methyl $\alpha - $ cyanoacrylate
D: Polyethyl methacrylate

Answer 1

Hint: Super glue or crazy glue is an adhesive. Adhesive is a material that is able to join two surfaces. These two surfaces may or may not be of the same material. This type of glue is not water based like other glue which is used commonly.

Complete step by step answer:
Super glue or crazy glue is an adhesive. An adhesive is a material which is used to join two surfaces. Glue that we use in our daily life is water based but super glue is not water based. This glue is made up of an acrylic resin. Industrial name of super glue or crazy glue is cyanoacrylate glue. The main ingredient of this glue is cyanoacrylate. Cyanoacrylate is an acrylic monomer. For cyanoacrylate glue to work as adhesive moisture should be present on the bonding surfaces. Without the presence of moisture cyanoacrylate glue doesn’t work. Super glue or crazy glue is basically poly methyl $\alpha - $ cyanoacrylate.
So, correct answer is option C.

Additional information: Attractive forces that exist between molecules of the same material are called cohesive forces and the attractive forces that exist between the surfaces of different materials are called adhesive forces. Cohesive force of water is due to polarity of water.

Note:
Super glue or crazy glue is a very strong adhesive even metal surfaces can also be joined with this glue. Medical cyanoacrylate adhesive is also called surgical glue. This glue can be used on cuts to stick human skin.
