Question

The compound which does not contain ionic bond is:

• A. NaOH
• B. HCl
• C. $K_{2}S$
• D. LiH

Answer 1

The correct option is B HCl

The bond present in $HCl$ is a polar covalent bond. ${}^{\prime }C{l}^{\prime }$ having higher electronegativity, it pulls the pair of electrons more towards itself causing a slight charge to develop on the atoms. So ${}^{\prime }{H}^{\prime }$ get a slightly positive charge and $Cl$ gets a slight negative charge. So it is a polar covalent bond.
