Determine whether each molecule given below is polar or nonpolar. of2
sergejj [24]

Answer : The molecule OF_2 is a polar molecule.

Explanation :

Polar molecule : When the arrangement of the molecule is asymmetrical then the molecule is polar.

Non-polar molecule : When the arrangement of the molecule is symmetrical then the molecule is non-polar.

The given molecule is, OF_2

The electronegativities of oxygen and fluorine are different. The molecular geometry of OF_2 is bent. As, Fluorine is more elctronegative than the oxygen. So, the arrows putting towards the more electronegative element i.e, fluorine. These arrows do not balance each other. Due to this, the asymmetrical arrangement of these bonds makes the molecule polar.

Hence, the given molecule OF_2 is polar.

Arturiano [62]
These are main components of Industrial Smog. Smog is air pollutant. Main sources of Smog are 1) Coal, 2) Transportation Emission, 3) Natural Causes. Those areas are mainly effected which are located in Industrial Zones and those which has high traffic density. Cities like Delhi, Beijing, London, Maxico City, Log Angeles, Tehran e.t.c are reported to be highly effected by smog. Among these polutants, CO₂ is the main source of Global Warming, CO has adverse effects on human health as it has 200 times more potency to bind with Hemoglobin compared to Oxygen, SO₂ when present in air reacts with water producing acid rain e.t.c.
