Question

Which of the following compounds is held together by ionic bonds? -​

Answer 1

Answer:

MgCl2

Explanation:

Mg - 12 - 2,8,2

Cl - 17 - 2,8,7

so, there are 2 chlorine so, Mg complete share 1 electron to one chlorine and 2 electron to 2nd chlorine.

Answer 2

Out of the given options, only MgCl2 is held together by ionic bonds.

MgCl2 is formed by the transfer of electrons from magnesium (Mg) to chlorine (Cl), resulting in the formation of Mg2+ cations and Cl- anions, which are held together by ionic bonds.

SO2, CH4, and NH3 are not held together by ionic bonds but instead have covalent bonds.

SO2 has a polar covalent bond, while CH4 and NH3 have nonpolar and polar covalent bonds, respectively.

A colourless gas or liquid with a pungent smell called sulphur dioxide, or SO2.

It is produced by smelting mineral ores that contain sulphur and burning fossil fuels (coal and oil) (aluminium, copper, zinc, lead and iron).

Sulfuric acid is created in water by the sulphur dioxide's fast dissolution.

chloride of magnesium an inorganic substance made up of two chloride ions and one magnesium ion.

Being a source of magnesium ions, which are necessary for numerous biological processes, the substance is employed in medicine.

The N-H bonds in NH3 provide it Hydrogen Bonding Intermolecular Forces, which is why it ranks highest. Neither of those exist in CH4. It only possesses weak London Dispersion forces.
