A π bond could be formed from the overlap of which two orbitals? A) two sp² hybrid orbitals B) a 1s and a sp² hybrid orbital C) a sp and a sp² hybrid orbitals D) two unhybridized p orbitals

D) two unhybridized p orbitals

Explanation:

In covalent bond, to form a bond, each of the two participating atoms would put down an  unpaired electron to be used in forming a shared pair of electrons between them.

There are two types of covalent bonds:

A sigma bond

A pi bond

A sigma bond is formed when a hybrid orbital (sp,sp² and sp³) overlaps with another hybrid orbital or with s- or p- orbital.

A pi bond is formed when a p-orbital overlaps with another parallel p-orbital laterally. This implies that ,a  π bond could be formed from the overlap of two unhybridized p orbitals.

explanation:

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
