Question 15

One of the chemical techniques used in crime scene to make fingerprint visible is by using cyanoacrylate. Surfaces where invisible fingerprints may be found, when exposed to cyanoacrylate fumes will make the fingerprints visible in white 3D matrix. Based on the cyanoacrylate structure in Figure below:

i) How many sigma bonds and pi bonds exist in the cyanoacrylate? ii) State the molecular shape with bond angle for Ca and Ob.

CH2 N=Ca .C CH3 O
