Pentane with molecular formula $$C_{5} H_{12}$$ contains :

A5 covalent bonds.
B12 covalent bonds.
C16 covalent bonds.
Correct Answer
D17 covalent bonds.

Solution

In pentane $$C_{5}H_{12}$$, there are 12 $$C-H$$ covalent bonds and 4 $$C-C$$ covalent bonds. Therefore, total number of covalent bonds in pentane are $$12+4 = 16$$.
