Which compound contains both ionic and covalent bonds? a) hbr b)cbr4 c)nabr d) naoh

The correct answer is Option d.

Explanation:

Ionic bond is formed when there is complete transfer of electrons from one atom to another. The atom which looses electrons is known as electropositive atom and the atom which gains electron is known as electronegative atom. Ionic compound, when dissolved in water will dissociate into its respective ions.

Covalent bond is defined when there is sharing of electrons between the two atoms forming a compound. It does not dissociate into its respective ions, when dissolved in water.

From the given options, the compound having both ionic and covalent bonds is NaOH.

Here, covalent bond is present between O and H forming ion.

When NaOH is dissolved in water, the equation follows:

As, it gets dissociated into its ions, therefore ionic bond is also present.

Hence, the correct answer is Option d.

the awnser is group 12
