What is the vsepr shape of h2co3

Answer : The shape of is, trigonal planar.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule.

When we are determining the shape of a molecule then it is important to draw a Lewis-dot structure and for drawing a Lewis-dot structure we should know that how many total number of valance electrons present in a given compound or a molecule.

The given molecule is,

As we know that hydrogen has '1' valence electrons, carbon has '4' valance electrons and oxygen has '6' valence electron.

Therefore, the total number of valence electrons in = 2 + 4 + 18 = 24

Now we have to determine the hybridization of carbon in

Number of bond pairs = 3

Number of lone pairs = 0

Number of atomic orbitals around carbon atom = 3 + 0 = 3

So, hybridization will be  and the shape is, trigonal planar.

The Lewis-dot structure is shown below.

Lithium is an element that has an electronic configuration of 2,1. So when forming bonds, it tries to release one of its electrons in the last shell to reach the octet state. Normally when atoms release electrons they get positive charge since the number of protons which bear positive charge, is higher than number of electrons which bear negative charge. So when reaching its octet state, lithium gains positive charge!

Hope this helps! Tbh am not good at explaining. If u have any doubts, ask me!
