Chapter 12: Q12.69P (page 496)

A water molecule can engage in as many as four H bonds. Explain.

Short Answer

Expert verified

A water molecule can engage as many as four H-bonds. This is because of the presence of two electron-donating H atoms and two electron-donating lone pairs of oxygen atoms.

Step by step solution

01

Water molecule

A water molecule is a bent structure that consists of two oxygen lone pairs of electrons and two electron-accepting H-atoms.

02

Number of bonds

The electronegative oxygen present in a water molecule consists of two non-bonded lone pairs of electrons which can be used to donate the electron pairs to other nearby molecules. The two H-atoms present can be used for bonding with other electronegative atoms nearby.

Hence, water can engage a maximum of four bonds.
