1) What are type 3 molecules in the given compounds?

A) only C3H8
B) C₂H, and OCl₂
C) C3H8, Zn(NO3)2, and OCl
D) MgCl₂ and Zn(NO3)2

Answer:

Type 3 molecules in the given compounds include Zn(NO3)2 and MgCl₂.

Explanation:

A type 3 molecule is a covalent compound in which the central atom has more than 8 valence electrons. In the given compounds, only Zn(NO3)2 and MgCl₂ fit this criteria. These compounds violate the octet rule because Zn and Mg both have fewer than 8 valence electrons.
