Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
In alkanes ($C_{n}H_{2n+2}$), the total number of covalent bonds is calculated by summing C-C and C-H bonds.
Step 2: Meaning
Total bonds = $(n-1)$ C-C bonds + $(2n+2)$ C-H bonds = $3n + 1$.
Step 3: Analysis
For Butane ($n=4$): $(3 \times 4) + 1 = 13$ bonds. For Hexane ($n=6$): $(3 \times 6) + 1 = 19$ bonds.
Step 4: Conclusion
The number of covalent bonds is 13 for butane and 19 for hexane. Final Answer: (C)
