BH3 does not obey octet rule.
it has a total of six electrons only.
boron has three electrons in the valence shell and it accepts one electron from each hydrogen
BH3 is a planar molecule and is found only in the gaseous state.
BH3 dimerises to form B2H6 with 4 terminal hydrogens attached by normal covalent bonds and 2 hydrogen bridges , 3 centre 2 electron bonds. Once again in the dimer it does not obey the octet rule.
The Lewis structure of germanium chloride, GeCl4, consists of a germanium atom bonded to four chlorine atoms. The germanium atom has four lone pairs, while each chlorine atom contributes one lone pair. The structure follows the octet rule, and each atom has a complete valence shell.
In drawing a Lewis structure, each nonmetal atom (except hydrogen) should be surrounded by 8 electrons to achieve a full octet and satisfy the octet rule. This can be achieved through the sharing of electrons in covalent bonds or the transfer of electrons in ionic bonds.
In a Lewis structure, each bond typically represents 2 electrons, so the number of octets would depend on the number of bonds and lone pairs around the central atom. For most main group elements, the goal is to achieve an octet of electrons (8 electrons) around each atom, although there are exceptions for elements like hydrogen and helium.
The Lewis structure of carbononitridic chloride, or NCCl is as follows: A N atom is triple bonded to a C atom. The C atom is single bonded to a Cl atom. The N has one lone pair and the Cl has 3.
The Lewis structure for Cr (chromium) has a total of 24 valence electrons. It will have 6 single bonds with other atoms to satisfy the octet rule, with the remaining 10 electrons as lone pairs on the central chromium atom to complete its octet.
The Lewis structure of germanium chloride, GeCl4, consists of a germanium atom bonded to four chlorine atoms. The germanium atom has four lone pairs, while each chlorine atom contributes one lone pair. The structure follows the octet rule, and each atom has a complete valence shell.
A Lewis structure that violates the octet rule would be one where a central atom doesn't have an octet of electrons, but has less or more than eight electrons around it. Examples include molecules with an odd number of valence electrons, such as NO or radicals like NO2.

In a Lewis dot structure, the electrons which complete an octet but are not located between two atoms are referred to as lone pair electrons. These electrons are not involved in bonding with other atoms and are typically found on the central atom of the molecule.
The Lewis dot structure of chloroform (CHCl3) shows a carbon atom surrounded by three hydrogen atoms and one chlorine atom, all connected by single bonds. Each hydrogen atom contributes one electron and the chlorine atom contributes seven electrons to form a total of eight valence electrons around each atom, satisfying the octet rule.
In the Lewis structures of ozone, each oxygen atom has a full octet of electrons, satisfying the octet rule. Additionally, ozone exhibits resonance because the double bond can be located on different oxygen atoms, resulting in two equivalent resonance structures.
The Lewis structure of a fluorine molecule (F2) consists of a single bond between the two fluorine atoms, with each fluorine atom having three lone pairs of electrons around it. Each fluorine atom has a total of 8 electrons, following the octet rule.
The Lewis dot structure for SeTe3 will have selenium (Se) in the center bonded to three tellurium (Te) atoms. Each Te atom will be bonded to the Se atom by a single bond, and there will be lone pairs on the tellurium atoms to satisfy their octet.
There are two bonds shown in the Lewis structure of O2, one single bond between the two oxygen atoms. Each oxygen atom satisfies the octet rule by sharing two electrons.
