Explanation:

• Question 31: Sodium (a metal) donates an electron to chlorine (a non - metal) in NaCl. Ionic bonds are formed by the transfer of electrons from a metal to a non - metal. Hydrogen bonds are weak intermolecular forces (not chemical bonds in the traditional sense for forming a compound like NaCl). Covalent bonds involve sharing electrons (usually between non - metals). Metallic bonds are between metal atoms.
• Question 32: Ionic bonds involve the transfer of electrons (e.g., from a metal to a non - metal). Covalent bonds involve sharing electrons. Ionic bonds can occur between metals and non - metals. Ionic bonds are generally stronger than many covalent bonds (e.g., in terms of melting and boiling points of ionic compounds compared to simple covalent molecules).
• Question 33: For simple binary compounds like \(AlBr_3\) (a metal - non - metal compound), we name the metal first (aluminum) and then the non - metal with the suffix '-ide' (bromide). The prefixes like'mono -'and 'tri -'are not used for simple ionic compounds (they are used for covalent compounds like \(CO_2\) - carbon dioxide, but not for \(AlBr_3\)).
• Question 34: Ionic bonds (due to electrostatic forces between ions), covalent bonds (sharing of electrons), and metallic bonds (sea of electrons around metal cations) are all relatively strong chemical bonds. There is no general rule that one of them is the weakest among these three in a simple comparison for all cases described in basic chemistry (unlike hydrogen bonds which are weaker intermolecular forces).
• Question 35: The octet rule states that atoms are stable when they have eight electrons in their outer shell (either by gaining, losing, or sharing electrons). It does not refer to the number of bonds (e.g., carbon can form 4 bonds to get an octet) or the way electrons are shared (covalent sharing is just one way to achieve an octet).

Answer:

• 31) A. Ionic Bond
• 32) D. They involve the transfer of electrons
• 33) B. Aluminum bromide
• 34) D. They are equally strong
• 35) A. Atoms are stable with eight electrons in their outer sh
