Question
1.) How many ? bonds and ? bonds does the CO2 molecule have?
2.)Which of the following is not a valence bond concept?
c.) A pair of electrons in a bond is shared by both atoms.
d.) Atomic orbitals on two atoms may overlap to form antibonding orbitals.
3.)Draw the electron-dot structure for CHClO.
4.)In the molecule ClF5, chlorine makes five covalent bonds. Therefore, five of its seven valence electrons need to be unpaired. The orbitals with the same energy are known as degenerate orbitals. For example, the p subshell has three degenerate orbital, namely, px, py, and pz.
How many degenerate orbitals are needed to contain seven electrons with five of them unpaired?
5.B) What types of orbital overlap occur in cumulene?
a.) The greater the overlap between the orbitals on two atoms, the stronger the bond. B.) Lone pair electrons are in atomic orbitals or in hybrid atomic orbitals.c.) A pair of electrons in a bond is shared by both atoms.
d.) Atomic orbitals on two atoms may overlap to form antibonding orbitals.

5.How many ? and ? bonds are present in a molecule of cumulene?
5.B) What types of orbital overlap occur in cumulene?
Explanation / Answer
ANSWER 1:there are main 3 types of bond in chemistry.
1. Ionic bond: due to electon transfer from metal to nonmetal.
2. Covalent bond: due to sharing of electron between two or more nonmetals.
3. metallic bond: due to delocalisation of electron among metal ions.
CO2 molecule have covalent bond as the electron shared between carbon and oxygen for the formation of co2 molecule.And carbon and oxygen both are nonmetal too.
