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?\n- single\n- double\n- triple\n- quadruple
Answer
Answer:
A. single
Brief Explanations:
Carbon has 4 valence - electrons. If the last carbon atom of an unsaturated fatty acid is bonded to two hydrogen atoms and one carbon atom, it has used 3 of its 4 valence - electrons. To complete its octet, the bond between the last carbon and the other carbon atom must be a single bond.
