Question

if the last carbon atom of an unsaturated fatty acid is bonded to two hydrogen atoms and one carbon atom, what type of bond must exist between the last carbon and the other carbon atom?
o single
o double
o triple
o quadruple

Explanation:

Carbon atoms have a valence of 4, meaning they form 4 bonds. If the last carbon atom is bonded to two hydrogen atoms (each hydrogen forms 1 bond) and one other carbon atom, the bond between the last carbon and the other carbon must be a single bond to satisfy the valence of carbon (2 + 1+1 = 4).

Answer:

single
