Answer:
1) False
2) False
3) True
4) True
5) False
Explanation:
1. Two sigma bonds comprise a double bond: False
Two sigma bonds are not possible between two atoms . There will always be one pi bond or two bonds with one sigma bond
2. A triple bond consists of one pi bond and two sigma bonds.
Two sigma bonds are not possible between two atoms . There will always be one pi bond or two bonds with one sigma bond
3. Bonds formed from atomic s orbitals are always sigma bonds. True
There is always an head to head overlapping possible with s orbital
4. A pi bond restricts rotation about the sigma-bond axis.
True.
5. A pi bond consists of two pairs of electrons.
False
Each bond can have one pair of electrons

C) A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons
Explanation:
The statement that best explains the behavior of chlorine is that its atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
- To form an ionic bond, two atoms combines together via electrostatic attraction between them.
- Ionic bonds are formed between metals and non-metals.
- The large electronegativity difference between the two specie is the driving factor.
- In forming NaCl compound, Na donates electron which is accepted by Chlorine.
- This leaves a positive charge on Na and a negative charge on chlorine and the ensuing electrostatic attraction forms an ionic bond.
To form the covalent bond, the chlorine shares their valence electrons between themselves. They have an equal affinity for these electrons and this leads to the formation of a non-polar covalent bond
