How many hydrogen atoms are present in a five-carbon hydrocarbon molecule with four of the carbons linked by a single covalent bond, and with the fifth carbon attached by a single bond as a branch to the second carbon in the chain?

Question

Quizplus · Accepted Answer

The molecule described is a branched alkane with five carbon atoms. Alkanes have the general formula CnH2n+2. Since there are four carbons in the main chain and one as a branch, the total number of carbons is still five (n=5). Plugging this into the formula gives C5H2(5)+2 = C5H12, indicating there are 12 hydrogen atoms.
