Concept explainers
Interpretation:
To choose the correct option that does not correctly describe the model of HCl that is shown in figure.
Concept introduction:
A covalent bond is expressed in the formula by placing a bar between the atoms bonded together. A covalent bond is non polar and non-ionized because in its formation electrons are not transferred from one atom to other.
Answer to Problem 17STP
The incorrect statement is A.
Explanation of Solution
There is a polar covalent bond between hydrogen and chlorine. In this bond hydrogen and chlorine share electrons unequally. Chlorine is more electronegative than hydrogen thus it pulls the electrons more tightly than hydrogen and gets partial negative charge. Hydrogen gets positive charge. Thus option A. is an incorrect statement.
B. Chlorine has stronger attraction for electrons than does hydrogen in H-Cl bond.
C. The electrons in the HCl bonds are shared equally.
D. HCl compound dissolves in a polar substance.
E. Chlorine is the more electronegative atom than hydrogen in H-Cl bond.
