Question

what is the lewis dot structure for NCCOH

the condensed version to determine hybridization

Answer 1

Answer:

STEP BY STEP DRAWING LEWIS STRUCTURE:

1. Write all molecules with their valence electrons. As we can see nitrogen is 3 electrons short of noble gas configuration, oxygen is 2, carbon is 4 and hydrogen is 1. Hence we arrange the electrons in such a way that each atom shares 'n' number of electrons, where is n = noble gas configuration - valence electrons.

2. Now we draw circles showing bond pairs.

3. Counting the number of electrons, Nitrogen, carbon(1) and oxygen has 8 shared pairs of electrons each. Hydrogen and C(2) need one electron each to complete their noble gas configuration. Hence, we rearrange the atom and complete the structure.

4. Each pair of electrons constitutes on bond hence, it can be written as N=C-(H)C=O.

The above diagram is a lewis dot structure for NCCOH.

Explanation:

Lewis dot structures are diagrams that describe the chemical bonding between atoms in a molecule and display the total number of electrons in the valence shell. These electrons are paired up to show bond pairs and lone pairs present in each of the atoms that constitute the molecule.

To find the hybridization of an atom we find its steric number:

The steric number = the number of atoms bonded to the atom + the number of lone pairs the atom has.

There are few modifications to this formula depending on the type of molecule.

If the steric number is 4, the atom is sp3 hybridized. If the steric number is 3, the atom is sp2 hybridized.
