An alkane with 7 carbon atoms contains _ hydrogen atoms.
Correct answer: A. 16
- A. 16
- B. 14
- C. 20
- D. 18
Explanation
An alkane with the general formula CnH2n+2, where n is the number of carbon atoms. For 7 carbon atoms, the formula is C7H2(7)+2 = C7H16, indicating 16 hydrogen atoms. The correct answer is therefore 16. Options B, C, and D are incorrect as they do not correspond to the correct formula for an alkane with 7 carbon atoms.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
