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
Brief Explanations:
Carbon has a valency of 4. 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 valency electrons. So, to satisfy its valency, it forms a single bond with the other carbon atom. Unsaturated fatty acids have double or triple bonds elsewhere in the chain, but in this case, the bond between the specified carbon atoms is single.
Answer:
single
