NO3- , NO2- NO2. and NO2+
NO2- < NO3- < NO2 < NO2+
For NO2-, the molecule is bent but we have 1 lone pair on nitrogen. Lone pair electron repulsion is more than the bonding electrons so the bond angle will be less than 120o.
In NO3-, there is no lone pair of electrons, all are bonding pairs leading to an ideal bond angle of 120o.
In NO2, the one lone electron exerts a less repulsion than a lone pair of electrons, so two bonding oxygen atoms are able to spread out more leading to bond angle greater than the ideal of 120o.
In NO2+, there is no lone pair, only bond pairs so the molecule is linear leading to a bond angle of 180o
Answer:
The classic example of immiscible liquids is oil and water. ... Oil is a non-polar molecule, so when you put the two liquids together, they do not mix. In addition to enthalpy, water is a special case where entropy also prevents mixing in what is known as the hydrophobic effect.
