Answer:
H---H and Cl---Cl bonds are broken and H---Cl bonds are formed.
Explanation:
The reaction between Hydrogen and Chlorine to produce HCl is:
[tex]H_{2} + Cl_{2}[/tex]⇒ [tex]HCl[/tex]
In this reaction the reactants are [tex]H_{2}[/tex] and [tex]Cl_{2}[/tex].
The product is HCl.
The bonds existing in the reactants are
1) H---H bond in [tex]H_{2}[/tex] (Non polar and covalent bond)
2)Cl---Cl bond in [tex]Cl_{2}[/tex] ( Non polar and covalent bond)
The bonds existing in product is/are:
1)H---Cl bond in HCl (Polar and covalent bond)
So all the chemical bonds in the reactants are broken to produce the chemical bonds in the products
In other words,
The H---H bonds and Cl---Cl bonds are broken to produce H---Cl bonds.
