Question

Pentane has the molecular formula ${\mathrm{C}}_5{\mathrm{H}}_{12}$. It has?

• A. $5$ covalent bonds
• B. $12$covalent bonds
• C. $16$ covalent bonds
• D. $17$ covalent bonds

Answer 1

The correct option is C

$16$ covalent bonds

The explanation for the correct option:

Option(C):$16$ covalent bonds

• A covalent bond is known as the type of chemical bond that involves the sharing of electron pairs between atoms, in which the electron pairs are called as shared pairs or bonding pairs
• The compound pentane is made up of two words ‘pent’ and ‘ane’, which suggest it has 5 carbons and it is an alkane.
• The molecular formula of pentane is given by ${\mathrm{C}}_5{\mathrm{H}}_{12}$, which depicts that the compound consists of $12$hydrogens.
• Hence, the structure of the given compound can be drawn as :

• As we can see from the figure, there are $5\mathrm{C}-\mathrm{C}$single bonds along with $14\mathrm{C}-\mathrm{H}$single bonds.
• Therefore, in total pentane, has $16$covalent bonds.

Hence, pentane has $16$covalent bonds, option (C) is the correct answer.
