Making a Lewis structure is the first and most crucial step for identifying various properties related to the bonding of the molecule. Hence, whenever bonding is mentioned besides a molecule or a compound your mind should immediately jump to the Lewis structure of the given compound.
What is the name of the acid that is made from sodium nitrite and mineral acid?
Quite unstable in nature, it was discovered by Scheele. It has a pungent odor and appears as a pale blue solution. Nitrous Acid is prepared by acidifying sodium nitrite and mineral acid. This is usually done at ice temperatures and the product HNO2 is produced in the reaction mixture itself.
Is HNO2 polar or nonpolar?
HNO2 is considered to be a polar molecule. When there is an electronegativity difference between different atoms within a molecule then polarity occurs. Polar molecules have an asymmetrical structure their net dipole moment equals zero. To find the polarity of HNO2, we first have to draw its Lewis structure.
Is oxygen a divalent atom?
Oxygen (O) is a divalent atom. So it is not counted. The only monovalent atom is H of which there is only one atom. Since HNO2 is a neural molecule (overall charge is 0), the charge of cation or anion will also be zero. Hence, H=1/2 [5+1] H=3, indicating that HNO2 is Sp2 hybridized.
