Explanation:

Step1: Recall bonding rules

Ionic compounds form between metals and non - metals, while molecular compounds form between non - metals.

Step2: Analyze each compound

• RbCl: Rubidium (Rb) is a metal and chlorine (Cl) is a non - metal, so it is ionic.
• NO: Nitrogen (N) and oxygen (O) are non - metals, so it is molecular.
• BaS: Barium (Ba) is a metal and sulfur (S) is a non - metal, so it is ionic.
• LiBr: Lithium (Li) is a metal and bromine (Br) is a non - metal, so it is ionic.
• LiCl: Lithium (Li) is a metal and chlorine (Cl) is a non - metal, so it is ionic.
• HBr: Hydrogen (H) and bromine (Br) are non - metals, so it is molecular.
• SO₂: Sulfur (S) and oxygen (O) are non - metals, so it is molecular.
• CO: Carbon (C) and oxygen (O) are non - metals, so it is molecular.

Answer:

Molecular: NO, HBr, SO₂, CO
Ionic: RbCl, BaS, LiBr, LiCl
