Ответ:
The compound in which the atom has unfilled valence shell of electron is
Explanation:
Valence electrons is defined as the electrons which are present in the outermost shell of an atom.
Lewis-dot structure is defined as the structure which represents the number of valence electrons around the atom. The dots represents the electrons.
For the given options:
Option 1:In the given compound, 2 electrons are shared between oxygen and each hydrogen atom. From the lewis dot structure,
Valence electrons in each hydrogen atom = 2
Valence electrons in oxygen atom = 8
The valence shell of both the elements is complete.
Option 2:In the given compound, 4 electrons are shared between carbon and each oxygen atom. From the lewis dot structure,
Valence electrons in each oxygen atom = 8
Valence electrons in carbon atom = 8
The valence shell of both the elements is complete.
Option 3:In the given compound, 2 electrons are shared between carbon and each hydrogen atom. From the lewis dot structure,
Valence electrons in each hydrogen atom = 2
Valence electrons in carbon atom = 8
The valence shell of both the elements is complete.
Option 4:In the given compound, 2 electrons are shared between boron and each chlorine atom. From the lewis dot structure,
Valence electrons in each chlorine atom = 8
Valence electrons in boron atom = 6
The valence shell of boron is not complete and has incomplete octet.
Hence, the compound in which the atom has unfilled valence shell of electron is
