What is the total number of moles of ' C ' atoms and ' H ' atoms respectively present in following n mole molecule ?
Options
- A4 n and 2 n
- B4 n and 4 n
- C6 n and 14 n
- D6 n and 6 n
Correct answer
C. 6 n and 14 n
Step-by-step solution
Interpreting the skeletal structure reveals a symmetrical C 6 H 14 molecule (2,3-dimethylbutane). Each terminal carbon bonds to three hydrogens, middle carbons bond to one hydrogen each, and methyl substituents each carry three hydrogens, totaling 14 hydrogen atoms. For n moles of C 6 H 14 , carbon atoms total 6n moles and hydrogen atoms total 14n moles, corresponding to option C .
